Work Description

Title: Citations to Open and Closed Access Articles: Treatment and Control Group Data Open Access Deposited
Attribute Value
  • These data are a random selection of 3,850 papers—peer-reviewed and review articles only; bibliographies, book reviews, corrections, discussions, editorials, letters, notes, etc. were not considered—from Deep Blue <> with original publication dates ranging from 1990 to 2013. These are matched with the 89,895 corresponding articles which remained closed, using the specific journal issue as a proxy for comparability of subject matter and quality. These citations are matched with data from citation information from Thomson Reuters’ Web of Science and Journal Citation Reports databases.
  • This random sample of OA articles comes from Deep Blue <>, the University of Michigan’s institutional repository service. Each OA article has the following characteristics: Prior to a known date (ranging from 2006 to the 2013) these articles—the final published version—were only available by subscription. After that date, they became freely available via Deep Blue. Meanwhile, other articles from the same journal issue as the now-OA article continued to only be available to subscribers. None of the OA articles were self-selected; authors did not choose to deposit the articles in question in Deep Blue, since we made them open via blanket licensing agreements between the publishers and the library.
