Europe PubMed Central now indexing PsyArXiv preprints

May. 14, 2021

Submissions to the community preprint server are now discoverable in Europe PMC’s robust archive of scholarly literature in the life sciences.

Charlottesville, VA — The Center for Open Science (COS) announces today that PsyArXiv preprints are now indexed in Europe PubMed Central (Europe PMC), an open global archive of more than 38.6 million scholarly publications in the life sciences. COS is thrilled to see the inclusion of PsyArXiv’s more than 14,000 preprints in Europe PMC, and notes the significance of the index in accelerating scholarly communication among the psychological science research community worldwide.

“Indexing PsyArXiv in Europe PMC means that psychological preprints will now be more discoverable than ever before. PsyArXiv users will benefit from the increased audience for their work,” said Katherine S. Corker, executive officer for the Society for the Improvement of Psychological Science, and Associate Professor at Grand Valley State University.

The move by Europe PMC signals the growing trust in the credibility of preprints and rewards PsyArXiv authors’ dedication to make their underlying data and supplemental materials openly available.

"We’ve seen an impressive rise in preprint popularity in the life sciences in the last few years – it’s a great way to rapidly communicate research results. [...] We hope that including preprint abstracts into Europe PMC search results, will not only enhance their discoverability, but also provide a community platform to explore some open questions,” said Johanna McEntyre, Associate Director of EMBL-EBI Services and Principal Investigator for Europe PMC.

COS’s decision to begin registering preprint DOIs with Crossref in 2018 paved the way for greater interoperability between software ecosystems, allowing repositories like Europe PMC to maintain global identifiers, effectively index content, and advance the dissemination of open access research.

“As the scholarly communication ecosystem shifts toward more acceptance and trust in preprints as a path to more open and accelerated dissemination of research findings, the OSF Preprints infrastructure will continue to focus on interoperability to enhance discoverability and reuse of preprints,” said Nici Pfeiffer, Chief Product Officer at the Center for Open Science.
