Until May 23, you have the opportunity to connect with researchers worldwide through preprint reading lists. Create, read, and share preprint reading lists to contribute to open knowledge.

How to Participate:

Create Your Reading List: Start today by building a list of at least five preprints.
Complete Your Reading: Download and read each preprint on your lists. Every download counts toward the Reading Marathon Award.
Get Your List Favorited: Share your list to collect favorites (e.g., on social media with #Preprints and #WorldBookDay2025, and we’ll amplify its reach on LinkedIn, Bluesky, and X). When others click the Favorite button on your list to endorse it, you'll receive favorites and unlock rewards through the Reader’s Choice Award.
