Over 15,300 full text COVID-19 now available in Europe PMC

In July 2020, Europe PMC began indexing the full text of COVID-19 preprints. The initiative supported by Wellcome, the UK Medical Research Council, and Swiss National Science Foundation, has now made over 15,300 full text COVID-19 preprints searchable and free to read, alongside peer reviewed articles.

Researchers can benefit from a greater number of results being returned for each query since Europe PMC search tool searches not only the abstracts but also the full text of articles and preprints. The full text of COVID-19 preprints are available for reading and reuse via a standard XML format, so if a preprint has an open license, it can be text mined programmatically, allowing deeper analysis of the COVID-19 literature.

Which servers are indexed?

Europe PMC currently indexes full text COVID-19 preprints from biomedical servers bioRxiv, and MedRxiv.  Adding to this, Europe PMC also includes full text COVID-19 preprints from Research Square, ChemRxiv, SSRN and from arXiv.


Preprint server

Disciplinary scope

arXiv

Multiple scientific fields, including quantitative biology

bioRxiv

Broad life & biomedical research (from animal behaviour and cognition to zoology)

ChemRxiv

Subject-specific, including biological and medicinal chemistry

medRxiv

Broad medical, clinical and related health sciences

Research Square

All scientific fields

SSRN

Multiple scientific fields including applied sciences, health sciences, life sciences, social sciences

Disciplinary scope was taken from ‘Preprint server directory’ at https://asapbio.org/preprint-servers 


 

Europe PMC uses the PDF freely available on these preprint servers to create the full-text HTML version of the preprint, which is later sent for author approval to display by Europe PMC.  A single query will access 15,000 preprints from across these 6 servers.

Data re-use

One of the aims of the project is to provide a unique corpus of COVID-19 research for current and future research. The COVID-19 full text articles in Europe PMC have already been used for data analysis in the following studies:


 

Future plans

Europe PMC is planning to index full text preprints from Preprints.org, Authorea and other preprint servers and platforms which include relevant COVID-19 content. To see an updated list of preprint servers check the ‘About preprint page’ on Europe PMC website.
