Use cases

• Competitive research intelligence - see who publishes in your field, where and how often
• Academic recruiting - find prolific authors by topic, institution and ORCID
• Publisher and journal analytics - measure output and citation impact per journal or publisher
• Literature reviews - export a structured corpus instead of copying references by hand
• R&D scouting - track which funders and institutions back a research area
• Bibliometrics and reporting - build citation and output dashboards

Why Crossref

Crossref is the infrastructure publishers use to mint DOIs, so its metadata is the source that indexing services build on. It is open, complete for participating publishers and free to query at scale, with deep pagination through cursors rather than a hard result cap.

Notes

• Affiliations and ORCIDs are only present when the publisher deposited them; coverage is good for recent works and thinner before roughly 2015.
• citationCount counts citations recorded within Crossref, which is usually lower than Google Scholar.
• Deep result sets are paged with Crossref cursors, so large exports stay reliable.
• "Newest first" orders by the date the record entered Crossref. Sorting by the printed publication date is not possible together with deep paging, and that field contains future-dated issues.
