Issues with PDF Retrieval

GrieferJones
I'm trying to import about 300 papers from two Google Scholar searches I've made; all the papers I want are already in my Google Scholar library, and so I can get them onto Zotero easily by exporting my library, but then there are no PDFs or snapshots attached.

When I select everything in Zotero and try to "Find Available PDFs," it tells me it can't find anything for all 300 articles. Trying to use the Zotero connector to import them page-by-page from my Google Scholar library (or from the search) gets me rate-limited pretty quickly.

Any tips? Or is my best option really to manually look everything up by title and find PDF versions?

    For items with a DOI, Find Available PDFs will download open-access PDFs, and for items with a DOI or URL, it will download PDFs you have IP-based access to (on-campus or using a VPN). It won't download gated files if you need to use a web-based proxy to access them.

    There's no particular reason to expect to be able to download hundreds of files at once without being blocked by something, even if you're on-campus. Publishers tend not to like that kind of thing.

    I understand that Zotero only has access to non-gated files, but it just seems unlikely that there's no open-access PDF for any of the 300 papers I have (unless one getting blocked causes the whole batch to get blocked for some reason).

    I think the problem is likely going to be the lack of DOI (which typically aren't in the google scholar metadata), which means that the UnPaywall lookup for openAccess papers fails.
    Use the DOI manager add-on to get DOIs for all/most of the items, then try again. https://github.com/bwiernik/zotero-shortdoi
