Purpose: To determine whether papers contributed by National Academy of Sciences (NAS) members perform differently than direct submissions. Data/Methods: 55,889 original papers published in PNAS from 1997 through 2014. Regression analysis measuring total citations, controlling for editorial track (Contributed, Direct, Communicated), date of publication, and paper topic. Main findings: Contributed papers consistently underperformed against Direct submissions, receiving 9% fewer citations, ceteris...
Analyzing 13,455 journals listed in the Journal Citation Report (Thomson Reuters) from 1997 through 2013, we report that the mean cited half-life of the scholarly literature is 6.5 years and growing at a rate of 0.13 years per annum. Focusing on a subset of journals (N=4,937) for which we have a continuous series of half-life observations, 209 of 229 (91%) subject categories experienced increasing cited half-lives. Contrary to the overall trend, engineering and chemistry journals experienced dec...

Does PubMed Central—a government-run digital archive of biomedical articles—compete with scientific society journals? A longitudinal, retrospective cohort analysis of 13,223 articles (5999 treatment, 7224 control) published in 14 society-run biomedical research journals in nutrition, experimental biology, physiology, and radiology between February 2008 and January 2011 reveals a 21.4% reduction in full-text hypertext markup language (HTML) article downloads and a 13.8% reduction in portable docu...

Does free access to journal articles result in greater diffusion of scientific knowledge? Using a randomized controlled trial of open access publishing, involving 36 participating journals in the sciences, social sciences, and humanities, we report on the effects of free access on article downloads and citations. Articles placed in the open access condition (n=712) received significantly more downloads and reached a broader audience within the first year, yet were cited no more frequently, nor e...

Objectives: The paper reviews recent studies that evaluate the impact of free access (open access) on the behavior of scientists as authors, readers, and citers in developed and developing nations. It also examines the extent to which the biomedical literature is used by the general public. Method: The paper is a critical review of the literature, with systematic description of key studies. Results: Researchers report that their access to the scientific literature is generally good and improving...

Critics of our randomised controlled study of open access publishing, article downloads, and citations said that we were too eager to report our findings and should have waited two to three years.1 Now, after three years, we …
