{"doi":"10.1073/pnas.2204074119","title":"Massive covidization of research citations and the citation elite","abstract":"Massive scientific productivity accompanied the COVID-19 pandemic. We evaluated the citation impact of COVID-19 publications relative to all scientific work published in 2020 to 2021 and assessed the impact on scientist citation profiles. Using Scopus data until August 1, 2021, COVID-19 items accounted for 4% of papers published, 20% of citations received to papers published in 2020 to 2021, and >30% of citations received in 36 of the 174 disciplines of science (up to 79.3% in general and internal medicine). Across science, 98 of the 100 most-cited papers published in 2020 to 2021 were related to COVID-19; 110 scientists received ≥10,000 citations for COVID-19 work, but none received ≥10,000 citations for non-COVID-19 work published in 2020 to 2021. For many scientists, citations to their COVID-19 work already accounted for more than half of their total career citation count. Overall, these data show a strong covidization of research citations across science, with major impact on shaping the citation elite.","journal":"Proceedings of the National Academy of Sciences","year":2022,"id":887,"datarank":0.6010999777848708,"base_score":4.007333185232471,"endowment":4.007333185232471,"self_citation_contribution":0.6010999777848708,"citation_network_contribution":0.0,"self_endowment_contribution":0.6010999777848708,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":54,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.059,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-07-07","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":11482,"name":"Eran Bendavid","orcid":"0000-0002-8364-4711","position":1,"is_corresponding":false},{"id":7559,"name":"Maia Salholz-Hillel","orcid":"0000-0003-1934-9504","position":2,"is_corresponding":false},{"id":5151,"name":"Kevin W.
