I would like to retrieve the doi for items for which I know the title, author, and year of publication. If I do
https://0-api-crossref-org.lib.rivier.edu/works?query.bibliographic="' . $title . ', ' . $author . ' ' . $year . '"&rows=1
I get a vast amount of information. All I want is the doi. Searches of your documentation and googling suggest that there is no way to do that, although that is hard to believe. Is it really not possible?
Hi Martin,
If you add “&select=DOI” to the end of any query, the results list will just include the DOI for each record.
It won’t return a single DOI, because the results are ordered by relevance score. For that reason, I wouldn’t actually suggest that you limit the results to only the DOI, without a way to identify whether you’re getting back the publication that you’re actually querying for.
You can add additional select parameters as needed, for example, title, container-title, and authors, which will give you a clearer sense of the matching item. Compare this to the above:
I hope that helps clarify. Please let us know if you have any other questions.

Wonderful — thank you! Now I see there is documentation at
https://0-api-crossref-org.lib.rivier.edu/swagger-ui/index.html#/Works/get_works
(I had previously looked at that page, but had not clicked on the “Works” tab — I guess I didn’t understand what “Endpoints that expose works related data” means. Wouldn’t it be clearer to say something nontechnical like “Queries that return publication information”?)
