Crossref provides metadata for publishers including titles, author names, ISSNs/ISBNs, abstracts, references, funding information, license information, full-text URIs, and updates/corrections. People use Crossref metadata for search/discovery, funding/author tracking tools, collaborative writing tools, and open datasets. National libraries also use it for analyzing publication statistics and negotiating with publishers. Crossref metadata helps research be found, cited, linked to, assessed, and reused.

1. Using metadata:
who, how and why

Basic metadata: titles; author names; ISSNs/
ISBNs, abstracts, references
Funding Information, Funder identifiers,
award numbers
License Information, License URIs

4. What do people
do with Crossref
metadata?

5. search, discovery, mining services

9. funders and funding tracking tools

11. author profiling tools

12. A collaborative writing tool
Built a tool based on
Crossref metadata to allow
authors to search and cite
without leaving the editor.

13. A free open dataset built on the Centre for Open
Science (COS) technology
Integrates Crossref metadata to join other sources
such as DataONE, 50+ library institutional
repositories.

14. “We would love to see rights-
declaration metadata. This is
invaluable to know whether it’s public
domain or copyrighted, and any
constraints for use.”

Digital data librarian in Research Data and GIS Services at
Washington University in St. Louis Libraries and
visiting program office for SHARE

15. National Library of Sweden
The Crossref metadata is presently used in two projects; Open APC Sweden and in our local analysis
database for publication statistics used in negotiations with publishers.
Open APC Sweden is a pilot project to gather data on open access publication costs (APC’s – Article
Processing Charges) from Swedish universities. The project is modelled from the German Bielefeld
University Open APC initiative, which is a part of the INTACTproject. After APC data has been
delivered to the APC system, scripts are run against the Crossref API to fetch information about
publishers and journals. A description of Open APC Sweden can be found here.
When building our local analysis database for publisher statistics, we download data from the
SwePub database, use the Crossref DOIs for API lookup against Crossref to add correct ISSN and
publisher data to the records and then match the records against a list of publisher serials. In this
way, we can get information about how much Swedish researchers have been publishing with a
certain publisher and use this data when negotiating conditions for open access publishing with the
publisher in question.
