CORD-19, a dataset of COVID-19 and coronavirus publications, has been made available alongside calls to help mine the information it contains and to create tools to search it more effectively. We analyse the delineation of the publications included in CORD-19 from a scientometric perspective. Based on a comparison to the Web of Science database, we find that CORD-19 provides an almost complete coverage of research on COVID-19 and coronaviruses. CORD-19 contains not only research that deals directly with COVID-19 and coronaviruses, but also research on viruses in general. Publications from CORD-19 focus mostly on a few well-defined research areas, in particular: coronaviruses (primarily SARS-CoV, MERS-CoV and SARS-CoV-2); public health and viral epidemics; molecular biology of viruses; influenza and other families of viruses; immunology and antivirals; clinical medicine. CORD-19 publications that appeared in 2020, especially editorials and letters, are disproportionately popular on social media. While we fully endorse the CORD-19 initiative, it is important to be aware that CORD-19 extends beyond research on COVID-19 and coronaviruses.<\/jats:p>","DOI":"10.1371\/journal.pone.0244839","type":"journal-article","created":{"date-parts":[[2021,1,7]],"date-time":"2021-01-07T21:40:55Z","timestamp":1610055655000},"page":"e0244839","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":59,"title":["A scientometric overview of CORD-19"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9806-084X","authenticated-orcid":true,"given":"Giovanni","family":"Colavizza","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"Costas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3170-3879","authenticated-orcid":true,"given":"Vincent A.","family":"Traag","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nees Jan","family":"van Eck","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thed","family":"van Leeuwen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ludo","family":"Waltman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,1,7]]},"reference":[{"issue":"7781","key":"pone.0244839.ref001","doi-asserted-by":"crossref","first-page":"130","DOI":"10.1038\/s41586-019-1717-y","article-title":"A new twenty-first century science for effective epidemic response","volume":"575","author":"J Bedford","year":"2019","journal-title":"Nature"},{"issue":"5","key":"pone.0244839.ref002","doi-asserted-by":"crossref","first-page":"460","DOI":"10.1038\/s41562-020-0884-z","article-title":"Using social and behavioural science to support COVID-19 pandemic response","volume":"4","author":"JJV Bavel","year":"2020","journal-title":"Nature Human Behaviour"},{"key":"pone.0244839.ref003","article-title":"Global health crises are also information crises: A call to action","author":"B Xie","year":"2020","journal-title":"Journal of the Association for Information Science and Technology"},{"issue":"1","key":"pone.0244839.ref004","doi-asserted-by":"crossref","DOI":"10.1038\/s41598-020-73510-5","article-title":"The COVID-19 social media infodemic","volume":"10","author":"M Cinelli","year":"2020","journal-title":"Scientific Reports"},{"issue":"1","key":"pone.0244839.ref005","doi-asserted-by":"crossref","first-page":"433","DOI":"10.1146\/annurev-publhealth-040119-094127","article-title":"Public health and online misinformation: Challenges and Recommendations","volume":"41","author":"B Swire-Thompson","year":"2020","journal-title":"Annual Review of Public Health"},{"key":"pone.0244839.ref006","doi-asserted-by":"crossref","first-page":"e13222","DOI":"10.1111\/eci.13222","article-title":"Coronavirus disease 2019: The harms of exaggerated information and non-evidence-based measures","author":"JPA Ioannidis","year":"2020","journal-title":"European Journal of Clinical Investigation"},{"issue":"10225","key":"pone.0244839.ref007","doi-asserted-by":"crossref","DOI":"10.1016\/S0140-6736(20)30461-X","article-title":"How to fight an infodemic","volume":"395","author":"J Zarocostas","year":"2020","journal-title":"Lancet"},{"key":"pone.0244839.ref008","unstructured":"EPI-WIN: WHO Information Network for Epidemics; 2020.
