Chemical Science: Preprint servers

Library resources organised at one place for students, academics and researchers from "Chemical Science (ChemS)"

What are preprints?

A preprint is a version of a research manuscript published before peer review.  Typically these documents and made freely available on large databases - preprint servers or repositories.  Publishing a preprint aims to speed up the process of disseminating research, to generate a conversation around research and gain feedback from others. 

Preprints have a number of benefits:

  • they enable researchers to establish an early claim for your research findings;
  • they signal to colleagues and other researchers your research interests and encourage collaboration and feedback;
  • you can publish the outputs such as posters, protocols, papers, and presentations that are not suitable for journal publication;
  • they provide evidence of authors productivity as well as improve their visibility;
  • preprints are open access, anyone can see your preprint and they are easily shared or discoverable using web search tools such as CORE and SHARE;
  • preprints are the fastest way to share and disseminate your research; 
  • easy access usually means more citations;


 Preprint repository in physics, math, computer science and related disciplines

Cornell University Library has provided operational support and stewardship for this open-access service since 2001

ChemRxiv: The Preprint Server for Chemistry


Introduced in 2017.

free service for disseminating and archiving unpublished preprints in chemistry

openly accessible, with no subscription fees for readers and no subscription charges for authors

It features over 3000 preprints from authors in 60 countries

Co-owned and collaboratively managed by ACS, RSC, German Chemical Society, Chinese CS, CS of Japan
