New OPENBIB Data Release
Launch of the new OPENBIB Data Release
In the last year, we, the Kompetenznetzwerk Bibliometrie, presented the initial OPENBIB data release, which contains selected and curated metadata from OpenAlex. In this blog post, we would like to introduce an updated OPENBIB data release, which is based on the OpenAlex snapshot from July 2025. Alongside updated curation pipelines, this data release is also featuring an author disambiguation system developed by GESIS - Leibniz Institute for the Social Sciences. We hope that this public release will make an important contribution to the bibliometric community.
Besides this release, the results of our ongoing investigation of OpenAlex are also regularly published in journals 12345 or as blog posts 67.
Data Release
Our release includes:
Datasets with a Focus on Germany:
- A curated set of publications from German research organisations indexed in OpenAlex according to the established Bielefeld Institutionenkodierung 89
- Additional funding information for articles of research projects funded by the German Research Foundation and reported to the programme “Open Access Publishing”, curated and expanded from the German Open Access Monitor
- A disambiguated author dataset for publications affiliated with German institutions developed by GESIS.
Datasets with a Focus on Global Developments:
- Publisher disambiguation with emphasis on imprints and mergers
- Preserved and enriched metadata about articles, institutions and journals covered by transformative agreements, curated and expanded from the initial data provided by the cOAlition S Journal Checker Tool
- A classifier for the identification of research articles (document type classification)10

A detailed documentation about the OPENBIB snapshot can be found on GitHub: https://github.com/kbopenbib/kbopenbib_data.
This dataset release is also available for KB users in the dedicated data infrastructure provided by the FIZ Karlsruhe and publicly on BigQuery as provided by the SUB Göttingen (dataset openbib).
What’s next?
We are planning to hold a Do-A-Thon within the next few weeks, which will be based on this public data release. Further details will be provided in the near future. We are looking forward to your feedback, as it helps us to refine and improve our curation processes!
