- Add the ability to extract a PDF URL from a given webpage using the
translation framework
- Add the ability to get open-access PDFs from landing pages from
Unpaywall data in addition to direct PDF URLs
- Use the above functionality to improve PDF retrieval for "Add Item by
Identifier"
- Add "Find Available PDFs" option to the item context menu to retrieve
PDFs for existing items from the DOI or URL page or using Unpaywall
data. The option appears for single items with a DOI or URL and no PDF,
and it always appears when selecting multiple top-level items (but
skips ineligible items).
PDF extraction from DOI/URL pages will currently only work with
unauthenticated access (i.e., on-campus or VPN, but not via a web-based
proxy).
