OVERVIEW
In the first major overhaul of the ASMS Bibliometric Project since 2020, we transitioned to using the open bibliographic data source OpenAlex. For the first time, we used ORCIDs to identify publishing members of the society. In total, we identified 83,445 publications co-authored by 10,609 past and current members of the ASMS. Visualizations of co-authorship and research topics are publicly available and interactively explorable in VOSviewer Online.
DATA AND METHODS
In this work we started from OpenAlex, a new and open bibliographic data source of scientific papers, authors and institutions1 (named after the Library of Alexandria of classical antiquity). Expanding on previous efforts2 , we then used a rule-based algorithm to match ASMS members to OpenAlex authors using name variants, email addresses, affiliations, and – new for the 2025 update – ORCIDs provided by 1,423 current members. An ASMS member was defined as anyone having been member of the society at any point in the over 10-year period between October 21, 2015 and April 7, 2025. We continued to accumulate journal publications published from 1980-2025 and that list at least two ASMS members as authors. After extensive manual clean-up and validation, we constructed a co-authorship network and visualized it using VOSviewer (version 1.6.20), with attraction/repulsion set to +/- 1 and clustering resolution to 1.00. To improve readability, peripheral members were projected to a rectangular perimeter of height 2.0 and width 3.0. As before, we also created and visualized a term co-occurrence network, based on the titles and abstracts of the co-authored publications, to explore research topics. Finally, we made all visualizations publicly available and interactively explorable using VOSviewer Online/
RESULTS
Based on 83,445 unique publications listing at least two current or recent ASMS members as authors, we constructed a co-publication network of 10,492 members, representing 86,274 co-member links and 251,888 co-member publication pairs (co-authorships). All of these numbers are more than twice those in the 2020 version of the network, suggesting a healthy growth of the field, society, and collaboration and publications between members of ASMS
