Search CORE by DOI or title, inspect the returned repository copies and their versions, and record the most recent version's repository and retrieval date in your source log. CORE aggregates open-access research outputs and offers discovery services for finding repository copies of scholarly work.
- Search CORE using the DOI first, since a DOI resolves through the Handle System to current information supplied for the identified object, commonly a registrant-maintained landing page. If the DOI returns no repository copy, repeat the search with the exact article title. Expected result: a list of candidate repository records to inspect.
- Open each returned record and check the version it holds, such as the accepted manuscript or the published version. Expected result: you can tell which copies represent later stages of the work.
- Select the most recent version for the update. Expected result: one copy is designated as the basis for your update.
- Record that copy's repository name and your retrieval date in the source log. Expected result: the update cites a specific repository copy with a dated retrieval, so a later reader can retrace the same record.
If CORE returns no copy, treat the result as unresolved and check the DOI landing page for a link to an open-access location. Unpaywall records describe open-access locations associated with a DOI, including host type, version, and license information when available, and they flag a selected best open-access location; use those fields to identify further repository copies to inspect.
