1. Introduction
Referees [
1], or peer reviewers, of international journals engage in a process of detailed examination by which authors’ submitted manuscripts are scrutinized, improved, and evaluated by these academics for the authors’ ability to satisfy the receiving journal’s editors and guidelines [
2]. The process of refereeing is synonymous with that of peer reviewing [
3]. To referee is the older term, used exclusively until after the mid 1960s when peer review became the more commonly used expression, coinciding with this activity being deemed essential for rigorous academic publications [
4].
Although previously considered ambiguous and recognized as a concept open to change [
5], what defines an international journal is the language of publication is one employed by researchers in a number of countries, the editorial board and pool of reviewers include members from a variety of countries, and the journal maintains comprehensive, clear and public standards for publication—practices that result in greater visibility and higher citation rates regarding international journals [
6]. International peer reviewed journals are generally held to a higher standard of review than what has been referred to as “megajournals”—open-access journals publishing manuscripts presenting scientifically trustworthy empirical results, yet doing so without considering the potential scientific contribution prior to publication [
7]. That peer reviewers of international journals be qualified, unbiased and available is the foundation of legitimacy regarding publication of the research conducted [
4,
6]. As such, it is important that peer reviewers—in volunteering their time to maintain a high standard for research publication—be able to assume each of the roles inherent to being a referee and they willingly and competently accept the responsibilities that coincide with them.
As a social concept, what is considered a role with respect to peer review mirrors the definition provided by the
Open Education Sociology Dictionary—a role is a position represented by a set of socially defined attributes and expectations determining appropriate behavior for an individual based on their status in relation to the group [
8]. In contrast, responsibilities, with respect to specific roles, according to the
Oxford English Dictionary are the state or fact of being in charge of or of having a duty towards a person or thing [
9]. In other words, responsibilities of peer reviewers represent a subset of their roles, developed and understood in relation to them.
Although peer review is ubiquitous and fundamental, and the number of articles regarding issues related to peer review was found to have advanced from 50 in 1974 to approximately 120 in 2014 [
10] and to have doubled between 2005 in 2015 [
11], there has been a paucity of recent research to clarify the roles and responsibilities of peer reviewers. What has been written has lamented that the journals have been insufficiently diligent in defining peer reviewers’ roles and responsibilities [
12].
One of the controversies surrounding the roles and responsibilities of peer reviewers is the appropriate length of time it should take to complete an adequate peer review, with the assumption that peer reviews are necessarily less effective if they are conducted quickly [10,[
13], rather than considering that the expeditious peer reviewer may instead be efficient and skilled in this regard. This type of assumption—that peer review is inevitably a long process [
3]—in part encourages substantial durations between the time of submission and that of publication, decreasing the timeliness of research while concurrently indicating to reviewers that conducting reviews is necessarily burdensome.
A peer review should take an average of 3 hours with only very complex topics taking hours more according to one author [
13]. Another, based on a survey by Publons, specified that 5 hours is the average reported by peer reviewers [
14]. A further author on peer review used research published over ten years ago for a reference claiming that the average reviewer spends approximately 10 hours reviewing a submission [
15]. As such, there is no agreement on how long peer review actually takes. From the perspective of this author as a frequent reviewer, peer review generally takes 3 hours except when the submission is over twenty-five pages or the author’s writing demonstrates poor language skills, requiring additional time to decipher the meaning of the text. These reasons are comparable to, though slightly different from, those put forward in a review of reviewers which found four reasons determining the length of time for completion of the review: (1) scientific quality and content of the paper, (2) reviewer expertise, (3) presence of supplementary material, and (4) clarity of the language and structure [
16]. Yet, regardless of which of the estimations is most accurate in time taken to review an article, Publons found a median of 16.4 days for reviewers to get their reviews back to the journal [
17] (p. 32). Such a median was unexpected by this author—as someone who returns reviews the same day the review process is begun—especially given that perception of review speed is a significant predictor of the author’s assessment of the quality of the review [
14].
After receiving scrutiny in the last few years [
11,
18], the publishing houses of journals have become responsive to the past criticism [
19] regarding the obscurity of their responsibilities expected of peer reviewers. As a result, in the estimation of this frequent peer reviewer, guidelines have become very clear in the information they provide to peer reviewers on their roles and responsibilities. This is evidenced by the various journals associated with their publishing houses now having a separate, detailed page on each of their websites devoted to the guidelines for reviewers (examples of these website are cited below, in the Method section). Nevertheless, there are researchers who continue to criticize journals for not being clear in their roles and responsibilities, yet basing their conclusion on research conducted before these changes were made to improve the transparency of the roles and responsibilities of peer reviewers [
20]. That these criticisms continue, in spite of the evidence that publishing houses are now making their guidelines obvious to peer reviewers and to authors, may be due in part to evidence demonstrating that few peer reviewers are themselves active researchers [
16]. As such, these continuing assertions regarding problems with the roles and responsibilities of peer reviewers are at best questionable.
Some authors have pondered the necessity of peer review [
21]. Yet, researchers continue to recognize its value—as was made clear in the 2018 Publons report that found 98% of respondents consider peer review to be either important (31.2%) or extremely important (66.8%) [
17] (p. 9). Still, regardless of the improvement to the guidelines that have been provided to reviewers by journals, with the number of international peer reviewed journals increasing [
4,
16], the pool of qualified peers reviewers is diminishing [
22]. The previous solutions that have been adopted to increase the pool of referees have concentrated on rewards to peer reviewers with respect to their role as peer reviewers [
23]. This has not had the type of success necessary to increase the pool of effective reviewers who can attend to the guidelines [
24]. Therefore, what is needed is a direct and more meaningful way to increase the pool of competent reviewers as those most qualified to assume the roles and responsibilities of peer review in relation to the guidelines of these journals. Since it is active researchers seeking publication who are most committed to publication in international journals, this author suggests that recognizing the peer reviewer foremost as a researcher is likely a more productive way to increase the pool of qualified peer reviewers to international journals than viewing them from the perspective of being a referee. Such recognition does not focus on the success of rewards in relation to the role of referee—a role that is not the primary focus of academics. Instead, the more substantial concern of scholars is the publication of their own research, so increasing the pool should be based on promoting academic scholarship, not professionalizing the role of reviewer.
Following from this understanding of the context of peer review, the aims of this study are to delineate the roles and responsibilities of peer reviewers in such a way as to decrease the lengthy period to publication and, as well, to increase the number of peer reviewers for maintaining international standards of journal publication. This study is valuable because it is important that research on the roles and responsibilities of peer reviewers of international journals be current—within the last five years—a period in which there has been little research on this topic. As such, the range of the roles and responsibilities of peer reviewers will be investigated in relation to the author’s own standards as an active researcher and frequent peer reviewer for various international journals of five distinct publishing houses. This will be undertaken in comparison with a 2019 publication evaluating the roles and responsibilities of referees based on the views of authors publishing on peer review [
12]. The major findings of this comparison will be noted and, following from them, advice will be provided to potential reviewers concerning what is expected of referees in undertaking their work. Recommendations will be offered for improving peer review with regard to both mitigating weaknesses in the process with respect to function and time taken to completion, and increasing the pool of qualified peer reviewers—recognized a decade ago as the fundamental issues with respect to peer review [
25].
4. Discussion
This discussion, with respect to the results, will be divided into two parts. The first will be a comparison of the guidelines of the five different publishing houses. The second will examine the ranking of the responsibilities of peer reviewers with respect to the views of the 224 authors who have written on peer review. The limitations of this examination will then follow.
4.1. Guidelines of the Five Publishing Houses
Of the five publishing houses representing journals for which the author has reviewed articles in the last half year of 2022, Dove is the least explicit in its guidelines for reviewers while Frontiers and MDPI both are most specific. How the latter two differ is that Frontiers is clear in telling reviewers they should follow the guidelines while MDPI does not provide this advice directly. Instead MDPI focuses on advising reviewers to read the submission carefully, which Frontiers does not. Nevertheless, Frontiers, unlike MDPI, states that the references should be checked for accuracy. In this regard, the way that Frontiers and MDPI differ seems to be with respect to their focus—Frontiers details a systematic approach to reviewing in all respects while MDPI seems to want reviewers to attend foremost to assessing the value of the content of the manuscript. This hypothesis regarding the differing focus of these two publishing houses with respect to peer review is further supported by Frontiers providing no explicit responsibility to summarize the paper when writing the review nor in reminding reviewers to comment without personal bias. Further justification is provided for concluding that MDPI is less concerned with reviewers taking an entirely systematic approach to reviewing in that it does not directly state that reviewers should let editors know when additional expertise is required to fully evaluate the submission.
It is only with respect to two responsibilities of peer reviewers thought important by this author that neither Frontiers nor MDPI provide explicit mention in their guidelines to peer reviewers: “Establish title/abstract/keywords suitability”, and “Identify if limitations are provided”. That reviewers should establish the suitability of the different parts of the front matter has become evident to this author in noting that there are instances when the title does not conform to the content of the submission, the abstract is poorly written, and/or the keywords are either not mentioned in the abstract or they are identified out of order (all keywords should be found in the abstract and listed in the order in which they there appear). These are problems the reviewer can bring to the attention of the authors during the review process and the importance of doing so has been recognized by one author in 2017 [
39]. If they are left for the editors to improve then the authors are not provided with an explanation regarding why the front matter is required to be changed—they are merely advised to make the changes by the copy editor. Still, the front matter will be attended to by the editors if the reviewer does not bring the proposed changes to the attention of the author. The importance of this responsibility differs from that of missing limitations. If the reviewer does not mention the need for a limitations section, the editors will not necessarily expect that the authors include one. This problem is a greater concern than that of the front matter deficiencies,. Without a limitations section, the authors have not provided a balanced approach to the assessment of their research. This is a major flaw of any submission. It is for this reason that—although it is helpful if reviewers identify the need to correct the front matter of a paper—it is imperative that they request a limitations section if none is provided. This lack of providing direct instructions to reviewers in the guidelines of both the Frontiers and MDPI publishing houses concerning the need for a limitations section is an important omission that requires amendment. Of the five publishing houses, only Springer unequivocally states in its guidelines that reviewers should determine if a limitations section is provided.
Regarding the responsibility that reviewers should “Establish title/abstract/keywords suitability”, there is only one publishing house that states directly that reviewers must be mindful of examining these aspects of the front matter—Wiley. The Wiley publishing house in most respects is the most particular in the responsibilities it expects through its guidelines for reviewers. Why it falls a little short of Frontiers and MDPI in this regard is that, unlike these two publishing houses, it neither pointedly tells reviewers to read the guidelines nor to follow them. Perhaps this publishing house, which is very detailed regarding its responsibilities in other ways, considers the need to read the guidelines and follow them to be self-evident. In contrast—from this author’s experience in reading the reviews conducted by the other reviewers of the same paper the author has been charged with reviewing (a privilege only available once the reviewer has submitted their own contribution to the review process)—many reviewers do not follow the guidelines, and this appears to be because they have not read them. Reviews based on evidence suggesting a lack of familiarity with the evaluating journal’s guidelines generally are not helpful to either the authors who have submitted the manuscript or the editors to whom the review is intended to provide guidance. In most other respects, the guidelines provided by Wiley take into consideration the necessary responsibilities as recognized by this author. What is missing is pointedly telling reviewers to: “Identify if limitations are provided”, “Consider suitability for journal’s audience”, “Summarize the argument presented” and “Advise on further expertise required”. In this regard, the Wiley publishing house appears to recognize the submission as an independent entity specific to one journal rather than a contribution to the larger world of academic publishing.
Although, as mentioned, Springer is the only publishing house that clearly states in its guidelines that the reviewers should check for the limitations section, in other regards, this publishing house, and Dove, are both more relaxed about the requirements for the review process they specify in their guidelines. For Springer, this flexibility with respect to what is required by the reviewer extends primarily to the supporting details of the submission. Checking references for accuracy and adequacy is not distinctly stated, nor is gauging the quality of the tables and figures. That the adequacy of the references is not necessarily checked means that there is a potential for work to be published with dated references leading to claims that cannot be currently supported. It should also be mentioned that although Springer and Dove don’t indicate checking the accuracy of references, the other publishing houses in most cases do not state that references, unless seminal, must be from the last five years. Only MDPI explicitly states references should be from the last five years—Wiley, in contrast, specifies the last ten years (much too broad a timeline for scientific articles, from this author’s perspective). This lack of focus on the details of the review process extends to there being no direct comment on the need for reviewers to determine if the study is reproducible. Dove, in being more informal in the guidelines to reviewers in general, does not direct reviewers to follow the guidelines, advise the editors on the ethical concerns of the paper, or indicate the reviewer’s own limitations as a reviewer. It is the only publishing house that does not ask that reviewers “Determine validity of question”. Reviewers are instead expected to provide a more general account of the strengths and weaknesses of the paper from a disciplinary perspective.
4.2. Ranking of Responsibilities of Peer Reviewers
In comparing the results of
Table 2 with those of
Table 3, it is immediately evident that the rankings that the 224 authors of papers on peer review gave to specific responsibilities considered necessary for peer reviewers differs substantially from the responsibilities this author considers important that are also found important by the five publishing houses. As pointed out previously, the 224 authors had little agreement among themselves. There is no responsibility that even half of the authors agreed was necessary. The largest agreement was by 92 authors. What is interesting with respect to
Table 3 is that the two tasks that the 224 authors thought most important, “Determine if interpretation is supported by the data” and “Provide constructive criticism”, are not part of
Table 3. The reason these points are not included is that they are both too broad and too vague. It is unclear in what way reviewers are to determine if the interpretation is supported by the data. Rather than provide this ambiguous statement, the data of
Table 3 instead breaks down, into a number of different steps, how this task might be completed throughout the process of conducting the review. This breakdown includes each of the responsibilities under the role of “Evaluate Submission” as laid out in
Table 1. Similarly, “Provide constructive criticism” is too obscure a task for reviews to know what is wanted and what should be avoided. In this respect,
Table 1, under the role of “Write the report”, outlines exactly what the responsibilities should be for the reviewer in this regard. When reviewers concentrate on their roles in evaluating the submission and writing the report as detailed in
Table 1, there is no need for the extraneous responsibilities that have first and second place in the rankings of
Table 2.
Nevertheless, there is important agreement among the rankings of the 224 authors and the five publishing houses if the rankings on
Table 3 that appear in the top 11 of
Table 2 are examined as they are the few where all the publishing houses explicitly include the responsibility as part of their guidelines. That said, only the ranks of 3, 5, 8, 9 and 11 appear. The others between 1 and 11 from
Table 2 are not found on
Table 3. For 4, 6, 7 and 10, the reason they don’t appear has more to do with how the authors (of the 2019 article from which the results were found) have made particular distinctions. Regarding the responsibility ranked as 4, “Timeliness: meet journal deadline”, this is very similar to “Determine if deadline can be met”, which ranks as item 24. As the publishing houses refer the need for authors to determine if the deadline can be met, this coincides with the responsibility set out by this author in
Table 1, rather than the idea of timeliness specified by the authors of the 2019 paper. However, they likely represent the same point and should not be differentiated as they are in the 2019 paper. The responsibility ranked as 6 in
Table 2, “Be expert in the subject area/matter/field and/or be familiar with/trained in research methods and statistics”, similarly is very close to “Establish expertise to do the review”, which ranks 25 in
Table 2. Given that the point ranked as 6 conflates a number of issues together and should have been broken down by the 2019 authors of the study—yet it contains the idea of the reviewer establishing their expertise to do the review—the responsibility of establishing expertise is one considered important in both
Table 2 and
Table 3. Again, “Determine validity/quality/technical merit/rigor”, which represents rank 7 on
Table 2 contains more than one task and should not have been listed as one point alone by the 2019 authors. With more than one task as part of rank 7, it is difficult to tell how this task differs from “Assess adequacy of methods in general”, which ranks as 9. Finally, “Evaluate study design’, which ranks as 10 in
Table 2, is too general to be a helpful instruction to peer reviewers. As with the item ranking 1 discussed above, responsibility 10 is too broad and reviewers are better informed to undertake each of the responsibilities in the role of “Evaluate Submission” from
Table 1.
There are six responsibilities listed on
Table 3 that have no corresponding rankings from
Table 2. These are, “Follow the guidelines”, “Read the submission carefully”, “Establish title/abstract/keywords suitability”, “Identify if limitations are provided”, “Summarize the argument presented”, and “Advise on further expertise required”. Generally, these responsibilities initially laid out in
Table 1 are not ones expressly stated in the guidelines and are found in fewer of the five publishing houses, with only one or two of these publishing houses directly advising reviewers to undertake these responsibilities. The exception is “Read the submission carefully”—four of the five publishing houses make of point of telling this to their peer reviewers in their guidelines. That none of the 224 authors on peer review thought it important to mention that the guidelines for peer review of the particular journal should be followed, and that few of the publishing houses include this advice in their guidelines, perpetuates the idea voiced by authors over the last fifteen years [
6,
12,
14,
16,
19,
20,
23,
25,
26,
28,
40,
41,
42,
43], that peer reviewers need training (an idea that is not supported by most journal editors [
30]). This is in contrast to expecting that they merely are obligated to read the guidelines to know what is important in conducting a peer review. Similar to the responsibility of “Establish title/abstract/keywords suitability”, neglecting to provide the editors with “Advise on further expertise required” prolongs the process of peer review. For this reason, even though neither the 224 authors nor most of the publishing houses exactly state these as responsibilities of peer reviewers (in that they don’t explicitly state them) there is insufficient guidance on including these ways of reducing the time between submission and decision. The neglect of most publishing houses in this study to decidedly tell reviewers in their guidelines that they should “Summarize the argument presented” means that the authors of the submission and the editors cannot be sure that the reviewer has understood the content of the manuscript—potentially leading to additional confusion and wasted time in the review process. This is why it is problematic that this responsibility did not receive a ranking in the study of 224 authors. Yet, by far the biggest omission by both those 224 authors in the 2019 study and the various publishing houses is regarding “Identify if limitations are provided”. Only Springer specifies that reviewers need to ensure that there is a limitations section to the submission under review. That none of the 224 authors considered this important and four of the publishing houses do not explicitly include this information in their guidelines means there is a substantial amount of research published that may not have been scrutinized to ensure limitations are covered in the discussion.
4.3. Limitations
The primary limitation of this study is that the material of
Table 1 is based on the author’s own perception as a frequent reviewer of various international journals. Although this author’s view is informed by a number of sources [31-33}, it still represents the summation of only one reviewer. Why this is a problem is that reviewers, by the nature of their task, work alone. As such, they don’t necessarily communicate their process of reviewing to others and receive feedback on the strengths and weaknesses of their established process. That said, when reviewers finish a review they are given the opportunity by the journal to read the reviews of the other reviewers who have refereed the same manuscript. Usually, this means the reviewer is permitted to read two additional reviews. It is from always taking the opportunity to compare reviews that this author considers the material created for this study in
Table 1 represented the most useful summation of the roles and responsibilities of reviewers.
Another limitation of this work is that research related to the views of authors on peer reviews concerning their roles and responsibilities was pertaining to one study conducted in 2019 of 224 authors of articles on peer review. This reliance on only one source for data was especially problematic because the authors of that paper differentiated the responsibilities and tasks of peer reviewers and did not consider the roles (although they believed they did in recognizing their distinction between roles and tasks). As such, by here evaluating the tasks and roles voiced by these authors as each being subsumed under responsibilities for the purpose of this evaluation, this author may have extended the context of responsibilities further than the 224 authors would have assumed. Furthermore, without the 2019 paper actually identifying the roles of reviewers (as defined in this paper’s Introduction), it remains unclear how the 224 authors conceptualized the roles of reviewers, and this could not be assessed. Further research in this regard could be to go back to the individual articles of the 224 authors and specifically look for what each has said about the roles of peer reviewers in contrast to responsibilities (or tasks).
The author acknowledged in the Materials section not being a statistician. Determining the accuracy and validity of statistical results takes expert knowledge and time when conducting a review. As such, given that this author does not possess the expertise to review statistical results, the author’s thought that reviews can be conducted in a timely manner under 16.4 days may be naïve. It’s possible that in certain cases the reviewer must design and create a specialized computer program to assess the accuracy of the manuscript’s results under review. If parameter definitions in the paper are vague, this may take time to decipher on the part of the reviewer. Therefore, this advice on how to decrease the time to a decision on the submission may be deficient in not having taken into consideration what may possibly be the most time-consuming aspect of peer review— representing a limitation of this assessment.
One aspect of the peer review process that was not considered was whether it makes a difference to the roles and responsibilities of peer reviewers for the journal to have a blind review or if the journal expects open identities and/or open reports [
17] (p.48). This possibility was not considered because, with respect to the journals for which this author reviews, most have the option of choosing whether the reviewer would prefer an open review or does not want to make their identity known. In this author’s own experience, the transparency of the review has been irrelevant to the roles and responsibilities the reviewer should assume—a view that has been supported by research which, however, also notes there may be a difference in how scholars in the humanities and social sciences view open journals in comparison with the sciences [
44]. As such, some of the 224 reviewers who participated in the 2019 study may not have held the same view regarding whether open review changes the roles and responsibilities of referees. That their view on this matter is unknown is a limitation.
5. Conclusions
Maintaining the quality of peer review, especially when the number of peer reviewers in comparison to submissions is decreasing, is necessary if the peer review process is to remain effective. Various authors since 2007, as noted in the Discussion, have considered that the best way to do this is to require all potential peer reviewers to undertake peer review training. Although this suggestion may establish consistency in the requirements for peer review, if the curriculum for peer review were standardized—and following it demanded—it neglects to recognize the efforts of journals in making their requirements for peer review readily accessible, transparent, extensive, detailed, and particular regarding their journal’s needs. As such, rather than necessitating that peer reviewers be trained, journals need only make their guidelines required reading for peer reviewers and that they advise peer reviewers to follow them when conducting the review.
Nevertheless, although there is much to be commended about the guidelines for reviewers offered by each of the five publishing houses examined, in some cases these guidelines still do not highlight a few key components of peer review. The first: the importance of author’s identifying research from the last five years has not been stressed sufficiently to peer reviewers by most publishing houses. Furthermore, peer reviewers have not been asked to focus on the vital importance of the limitation section to submissions. In this regard, peer reviewers have scrutinized submissions without effective attention being given to requiring that authors assess the weaknesses of their research. In following a recommendation to publishing houses that they include a focus on these important aspects, the current value of international publications and their veracity will be increased.
With respect to increasing the pool of reviewers—although one author has argued that there should be no obligation to review papers, as this demand may produce ill-conceived reports that are “misleading and useless” [
43]—this present author suggests, in contrast, that each corresponding author should review at least one other paper in their field before their accepted publication goes to press. Although this idea is in opposition to the above mentioned author, it is not a new idea. Furthermore, it has even been proposed that authors of a submission should review three other papers to compensate for the three reviews they have experienced in regards to their submission during the review process [
15,
19]. However, such a stringent requirement, although it would significantly increase the number of peer reviewers available, would at the same time increase the time to decision to a degree that likely would be detrimental to prompt publication in international peer reviewed journals. Since the actual purpose of peer review is to determine suitability for publication in a timely manner, rather than to calculate a fair distribution of hours devoted to peer reviewing, it would seem reasonable that the publication of research not be slowed down unnecessarily by expecting all authors with an accepted manuscript to then each review what would normally be three other manuscripts to match the number of peer reviews they experienced in the acceptance of their own submission. As a growing amount of scientific research is conducted in large teams [
45], there can be a very large number of authors for a particular publication. If, before an accepted paper is published every one of these authors were expected to conduct a peer review, the focus of the role of the journal would change from publishing to administering peer reviews. Therefore, the suggestion is to have only the corresponding author of an accepted publication conduct a peer review before publication to keep administration of these peer reviews manageable. This is a suggestion supported by recent research published in this journal [
46]. In this way, the pool of qualified peers reviewers would necessarily be increased while maintaining the aim of expeditious publication.
A median of 16.4 days for time to completion of peer reviews from the Publons survey of peer reviewers [
17] (p. 32) is unexpectedly long from this author’s perspective. In promoting timely research, every effort should be made by publishing houses to improve their guidelines so that this median time is reduced. As such, it would be helpful if these guidelines included the following responsibilities that this author has found useful in reducing the number of times that a submission requires revision: “Establish title/abstract/keywords suitability”, “Summarize the argument presented” and “Advise on further expertise required”. If all publishing houses asked reviewers to, (1) examine the front matter for errors and omissions, (2) summarize the content of the paper in the first paragraph of the review to indicate that the reviewer has understood the argument presented by the submission’s authors, and (3) provide advice to the editors that the reviewer is lacking in some area, the time to completion of reviews would likely be reduced.
The roles and responsibilities of referees of international peer reviewed journals have, in response to previous criticism by researchers, become detailed, comprehensive and transparent, as evidenced by the guidelines for peer review being specified on their own webpage for each of the publishing houses investigated. As such, the most effective thing a peer reviewer can do in understanding these roles and responsibilities—rather than undergoing general training on the peer review process—is to read these guidelines and follow them. Nevertheless, there remains room for improvement in these guidelines. The most important changes that should be made are that all publishing houses should specify the references of submitted work must be current within the last five years and that each submission be scrutinized to determine if it includes a limitations section. With the number of submissions continuing to increase, in order for these roles and responsibilities to be undertaken in a timely manner the pool of reviewers must be increased in a way that is relevant to these referees as researchers. By requiring each corresponding author to conduct a peer review before publication of an accepted submission, not only will the pool of qualified researchers be increased, it will be increased in a way that is relevant to the entire process of peer review in international journals.
In this tenth anniversary issue of Publications, it is hoped that this focus on the roles and responsibilities of peer viewers for international journals will exemplify the importance the peer review process continues to have for international journal publication, and this effort presented will be identified as an effective means for both making these roles and responsibilities evident while at the same time decreasing the time to completion and increasing the pool of qualified peer reviewers.
