By combining multiple open data sources, including cOAlition + S Journal Checker, Crossref, and OpenAlex, we present a novel approach that + analyzes over 700 agreements. Results suggest a strong growth in open access, + from 4.3% in 2018 to 15% in 2022. Over 5 years, 11,189 hybrid journals provided + open access to 742,369 out of 8,146,958 articles (9.1%). Authors who could + make use of transformative agreements contributed 328,957 open access articles + (44%) during this period, reaching a peak in 2022 with 143,615 out of 249,511 + open access articles (58%). While this trend was predominantly driven by the + three commercial publishers Elsevier, Springer Nature, and Wiley, open access + uptake varied substantially across journals, publishers, disciplines, and + countries. In particular, the OECD and BRICS areas revealed different publication + trends. In conclusion, this study suggests that current levels of implementation + of transformative agreements are insufficient to bring about a large-scale + transition to full open access.<\/jats:p>","DOI":"10.1162\/qss_a_00348","type":"journal-article","created":{"date-parts":[[2025,1,14]],"date-time":"2025-01-14T18:24:38Z","timestamp":1736879078000},"page":"242-262","update-policy":"https:\/\/doi.org\/10.1162\/mitpressjournals.corrections.policy","source":"Crossref","is-referenced-by-count":4,"title":["How + open are hybrid journals included in transformative agreements?"],"prefix":"10.1162","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5105-1463","authenticated-orcid":true,"given":"Najko","family":"Jahn","sequence":"first","affiliation":[{"name":"G\u00f6ttingen + State and University Library, University of G\u00f6ttingen, G\u00f6ttingen, + Germany"}]}],"member":"281","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"issue":"8","key":"2025032610360375100_bib1","doi-asserted-by":"publisher","first-page":"6761","DOI":"10.1007\/s11192-021-04059-x","article-title":"Publication + patterns\u2019 changes due to the COVID-19 pandemic: A longitudinal and short-term + scientometric analysis","volume":"126","author":"Aviv-Reuven","year":"2021","journal-title":"Scientometrics"},{"volume-title":"The + Budapest Open Access Initiative: 20th anniversary recommendations","year":"2022","author":"Babini","key":"2025032610360375100_bib2"},{"issue":"4","key":"2025032610360375100_bib3","doi-asserted-by":"publisher","first-page":"67","DOI":"10.23974\/ijol.2024.vol8.4.341","article-title":"Impact + of transformative agreements on publication patterns: An analysis based on + agreements from the ESAC registry","volume":"8","author":"Bakker","year":"2024","journal-title":"International + Journal of Librarianship"},{"issue":"26","key":"2025032610360375100_bib4","doi-asserted-by":"publisher","first-page":"9425","DOI":"10.1073\/pnas.1403006111","article-title":"Evaluating + big deal journal bundles","volume":"111","author":"Bergstrom","year":"2014","journal-title":"Proceedings + of the National Academy of Sciences"},{"issue":"8","key":"2025032610360375100_bib5","doi-asserted-by":"publisher","first-page":"1496","DOI":"10.1002\/asi.22709","article-title":"The + hybrid model for open access publication of scholarly articles: A failed experiment?","volume":"63","author":"Bj\u00f6rk","year":"2012","journal-title":"Journal + of the American Society for Information Science and Technology"},{"key":"2025032610360375100_bib6","doi-asserted-by":"publisher","first-page":"e3878","DOI":"10.7717\/peerj.3878","article-title":"Growth + of hybrid open access, 2009\u20132016","volume":"5","author":"Bj\u00f6rk","year":"2017","journal-title":"PeerJ"},{"issue":"2","key":"2025032610360375100_bib7","doi-asserted-by":"publisher","first-page":"93","DOI":"10.1087\/20140203","article-title":"How + research funders can finance APCs in full OA and hybrid journals","volume":"27","author":"Bj\u00f6rk","year":"2014","journal-title":"Learned + Publishing"},{"issue":"3","key":"2025032610360375100_bib8","doi-asserted-by":"publisher","first-page":"359","DOI":"10.1002\/leap.1558","article-title":"Article + processing charges for open access journal publishing: A review","volume":"36","author":"Borrego","year":"2023","journal-title":"Learned + Publishing"},{"issue":"2","key":"2025032610360375100_bib9","doi-asserted-by":"publisher","first-page":"216","DOI":"10.1002\/leap.1347","article-title":"Transformative + agreements: Do they pave the way to open access?","volume":"34","author":"Borrego","year":"2021","journal-title":"Learned + Publishing"},{"key":"2025032610360375100_bib10","doi-asserted-by":"publisher","DOI":"10.5281\/zenodo.4558704","article-title":"OA + diamond journals study.
