Search Crossref works (publications) by free-text query and/or filters.

Use cursor="*" for deep pagination beyond 10 000 results; the response includes next-cursor for subsequent pages. Mixing cursor with offset is not supported — when cursor is set, offset is dropped automatically.

Examples: search_works(query="machine learning", rows=5) search_works(filter="from-pub-date:2024-01-01,until-pub-date:2024-12-31", sort="published", order="desc") search_works(query="crispr", select="DOI,title,author,published", cursor="*")
