Query: No Deal: Investigating the Influence of Restricted Access to Elsevier
  Journals on German Researchers' Publishing and Citing Behaviours   In 2014, a union of German research organisations established Projekt DEAL, a
national-level project to negotiate licensing agreements with large scientific
publishers. Negotiations between DEAL and Elsevier began in 2016, and broke
down without a successful agreement in 2018; in this time, around 200 German
research institutions cancelled their license agreements with Elsevier, leading
Elsevier to restrict journal access at those institutions from July 2018
onwards. We investigated the effect of these access restrictions on
researchers' publishing and citing behaviours from a bibliometric perspective,
using a dataset of ~410,000 articles published by researchers at the affected
DEAL institutions between 2012-2020. We further investigated these effects with
respect to the timing of contract cancellations with Elsevier, research
disciplines, collaboration patterns, and article open-access status. We find
evidence for a decrease in Elsevier's market share of articles from DEAL
institutions, from a peak of 25.3% in 2015 to 20.6% in 2020, with the largest
year-on-year market share decreases occurring in 2019 (-1.1%) and 2020 (-1.6%)
following the implementation of access restrictions. We also observe
year-on-year decreases in the proportion of citations made from articles
published by authors at DEAL institutions to articles in Elsevier journals
post-2018, although the decrease is smaller (-0.4% in 2019 and -0.6% in 2020)
than changes in publishing volume. We conclude that Elsevier access
restrictions have led to some reduced willingness of researchers at DEAL
institutions to publish their research in Elsevier journals, but that
researchers are not strongly affected in their ability to cite Elsevier
articles, with the implication that researchers use a variety of other methods
(e.g. interlibrary loans, sharing between colleagues, or "shadow libraries") to
access scientific literature.
