“…"Studies relying on Unpaywall data should be aware that the reproducibility and comparability of their results are time dependent. "(Error) Jahn [2] looks at the same problem but from a wider angle and seems to be keeping track of Unpaywall snapshots from the past. In fact, Butler [3] ran into this issue, with Unpaywall designations changing halfway through the analysis and writing of their paper!…”

No deal: German researchers’ publishing and citing behaviors after Big Deal negotiations with Elsevier

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. We investigated the effect on researchers’ publishing and citing behaviours from a bibliometric perspective, using a dataset of ∼400,000 articles published by researchers at DEAL institutions between 2012–2020. We further investigated these effects with respect to the timing of contract cancellations, 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, with the largest year-on-year market share decreases occuring from 2018 to 2020 following the implementation of access restrictions. We also observe year-on-year decreases in the proportion of citations, although the decrease is smaller. We conclude that negotiations with Elsevier and access restrictions have led to some reduced willingness to publish in Elsevier journals, but that researchers are not strongly affected in their ability to cite Elsevier articles, implying that researchers use other methods to access scientific literature.

Zusammenfassung Maschinelle Verfahren als Instrumente, um die Open-Access-Transformation in Form von Publikationsdaten abzubilden, erfordern aufgrund enormer Datenvolumen strukturierte Datensätze, die eindeutig identifizierbar sind und sich vergleichen lassen. Zur Identifikation wissenschaftlicher und praxisorientierter Publikationen haben sich digital object identifier (DOI) durchgesetzt, doch längst nicht alle Publikationen sind damit ausgestattet. Anhand eines Datensamples der Pädagogischen Hochschule Zürich werden in dieser Studie ausgewählte Datenquellen für Monitoring-Verfahren analysiert, um Quoten für nicht-repräsentierte Publikationen zu berechnen und unbeabsichtigte Leerstellen sichtbar zu machen. Das Verstehen dieser Leerstellen eröffnet Lösungsansätze, wie diese vermieden werden können, um ein belastbares Open-Access-Monitoring sicherzustellen.
