The American Society for Microbiology (ASM) has earned recognition in Crossref’s Participation Reports for its exceptional metadata coverage among large publishing members––an achievement built on intentional change, technical investment, and collaborative work. In this Q&A, the ASM team shares what that journey looked like, the challenges they’ve tackled, and how centering metadata has helped them better connect research with the global scientific community.
The Crossref Board recently approved three recommendations for changes to our fees: introduction of a new lowest membership fee tier, removal of volume discounts for record registration, and normalisation of registration fees for peer reviews. The changes will be applied from January 2026.
This is the first outcome of the Resourcing Crossref for Future Sustainability (RCFS) program, launched in 2023, as a comprehensive effort to review all aspects of Crossref revenue and how we’re adapting to growth and the diversification of our membership. The program aims to make fees more equitable, simplify our complex fee schedule, and rebalance revenue sources.
This June, we presented at the Beijing International Book Fair (BIBF) and connected directly with our growing community in China. With a surge of interest from Chinese publishers and partners, it was clear: there’s a strong and rising curiosity around how metadata plays a vital role in maintaining the integrity of the scholarly record.
A DOI may refer to a journal or book (a title-level DOI), or to a specific article or chapter.
Journals and DOIs
Like a set of nesting dolls, a journal may be made up of volumes, each containing a number of issues, each containing a number of articles. You can assign a DOI at each level, for example:
journal-level-DOI (sometimes called the title-level-DOI) 10.5555/QYPF2031. Like an ISSN, it refers to the whole journal
volume-level-DOI 10.5555/FFFU4804
issue-level-DOI 10.5555/QKLE5634
article-level-DOI 10.5555/CNBT7653
The role of the journal-level-DOI, volume-level-DOI, and issue-level-DOI is to link persistently to a point in the journal structure. These DOIs do not have any associated content, and it does not cost anything to register these DOIs.
However, article-level-DOIs do have associated content, and therefore a fee applies to register these DOIs.
Books and DOIs
Like a set of nesting dolls, a book may be made up of chapters. Again, you can assign a DOI at each level, for example:
book-level-DOI (sometimes called the title-level-DOI) 10.5555/ZAAR1365. Just like an ISBN, it refers to the whole book.
chapter-level-DOI 10.5555/TFWD2627
Both book-level-DOIs and chapter-level-DOIs have associated content, and therefore a fee applies to register these DOIs.
