I am using the Crossref Unified Resource API and GET /journals/{issn}/works to retrieve metadata from 5 different journals. I request each journal individually and specify for example; from-pub-date:2022-01-01,until-pub-date:2022-12-31.
I am interested in a 10 year span from 2013 - 2023 and when i isolate the years from 2013-2021 everything works fine. However, for all 5 journals and every call for the years 2022 or 2023 i get “total-results”: 0.
Is the database not updated past 2021, or am I missing something?
Thanks for your message, and welcome to the community forum!
Yes, the REST API is updated with content from 2022, 2023, and 2024. We are and will continue to add records to it. What is the ISSN and journal title(s) in question? It sounds like the ISSN in question is just not being used in the 2022 and 2023 metadata. There may be legitimate reasons why that is the case.
