Preprints

Preprints

Research papers that appear prior to the completion of full peer review. They are not as extensively validated as peer reviewed publications and so their data or findings should not be used to inform clinical practice. However, the research they contain will be of interest to those seeking the latest or emerging research in their field. Preprints have proven to be very significant in the early dissemination of Covid-19 related work. Preprints are published on:

Preprint Servers, such as those which appear below. 

  • MedRxiv - Preprint server for Health Sciences
  • BioRxiv - Preprint server for Biology
  • ArXiv - Preprint server for the Sciences, including physics, computer science, quantitative biology, statistics and economics.
  • SSRN - preprints papers dedicated to Social Sciences. Since being acquired by Elsevier, it is claimed that the SSRN preprints are included in the SCOPUS database.

PMC (PubMed Central) has since June 2020 been making certain Preprints openly available on their database. 

Europe PMC - Searches across all these preprint sources, as well as other Open Access content, can be made on Europe PMC.
