PLOS announces partnership with EarthArXiv

Note: PLOS issued the following press release on Thursday, December 8, 2022

SAN FRANCISCO —The Public Library of Science (PLOS) today announced that it has partnered with EarthArXiv, which enables authors submitting to PLOS Climate, PLOS Sustainability and Transformation, and PLOS Water to post preprints with ease. Beginning next year, submitting authors will have the option to automatically forward their manuscript to the EarthArXiv preprint server, directly from our submission system.

PLOS sees preprints as integral to our mission of accelerating progress in scholarly research, and to our goal of increasing adoption of Open Science practices. Authors use preprints to establish priority, broadcast results, seek community feedback, and advance their careers. Early, transparent sharing via preprints disseminates new insights faster and increases efficiency across the entire research ecosystem.

“Researchers told us they needed a community-recognized solution for sharing preprints when submitting to PLOS Climate, PLOS Sustainability and Transformation, and PLOS Water. We’re thrilled to partner with EarthArXiv – hosted by the California Digital Library – to offer these research communities an integrated solution that meets their needs and enhances our author service,” said Iain Hrynaszkiewicz, Director of Open Research Solutions at PLOS.

EarthArXiv is a community-based server, governed by a diverse advisory council with representatives from many regions and institutions, and hosted by the California Digital Library (CDL), an organization committed to open scholarship.

Tom Narock, Co-Founder of EarthArXiv and a member of its Advisory Council adds, “The EarthArXiv preprint community welcomes PLOS as a new partner. We are excited to combine our joint interests in open-access research publication. Preprints allow colleagues to easily find, use, and review the latest research results. PLOS’ streamlined integration with EarthArXiv expands our open-access research offerings while making preprinting easier for Earth science researchers.”

EarthArXiv is PLOS’ third preprint server integration. Our previously established partnerships with bioRxiv and medRxiv have shown that preprint posting is a valued author service, and that making preprint sharing easy for authors increases their uptake. PLOS is now expanding the benefits of facilitated posting to more of the researchers and research communities we serve.

About the Public Library of Science

PLOS is a nonprofit, open access publisher empowering researchers to accelerate progress in science and medicine by leading a transformation in research communication. Since our founding in 2001, PLOS journals have helped break boundaries in research communication to provide more opportunities, choice, and context for researchers and readers.

About EarthArXiv

EarthArXiv (pronounced “Earth archive“) is both a preprint server and a volunteer community devoted to open scholarly communication. As a preprint server, EarthArXiv publishes articles from all subdomains of Earth Science and related domains of planetary science. EarthArXiv is not itself a journal and does not evaluate the scientific quality of a paper. Since it was launched October 23, 2017, the EarthArXiv preprint service has added more than three-thousand papers—preprints or postprints—to its repository.

About the California Digital Library (CDL)

Individually and collectively, the University of California libraries provide access to the world’s knowledge for the UC campuses and the communities they serve, directly supporting UC’s missions of teaching, research, and public service. The California Digital Library, situated within the UC Office of the President, provides transformative digital library services that amplify the impact of the libraries, scholarship, and resources of the University of California.
