Retrieving DOIs by title
A list of DOIs by title (top-level title, such as journal or book title, not article- or chapter-level title) may be retrieved using the following format:
https://doi.crossref.org/search/doi?pid=username:password&format=doilist&pubid=content type pubid
pid = your Crossref account username and password, or query services email address
content type = J for journals, B for books or conference proceedings, S for series
pubid = publication ID
The results returned match the title detail results from the depositor report, and include a list of all DOIs for the title, the owner prefix for each DOI, the timestamp used in the most recent deposit, and the data the DOI was last updated.
