Is there a tool that can retrieve subject area listings for a journal using an API I'm attempting to characterise a corpus of journal articles by their subject area and categories. I can do this for individual journals using e.g. The SCImago Journal &amp; Country Rank (https://www.scimagojr.com), but I'd like to retrieve the data in bulk. Does anyone know whether this data exists, or whether it's available via an API?
Not an API, but still machine-readable: Scopus provides an Excel file comprising the database's coverage, including each journal's disciplines and subject areas. See this page and click on &quot;Download the Source title list&quot;.
(Elsevier provides an API, too, so it is possible that you might obtain the same information through that venue.)
