Unpaywall is a service which tracks and links to Open Access scholarly content s available for free online (i.e. not behind a paywall).
The Stanislaus State Library has incorporated Unpaywall into the Sanislaus State Library OneSearch service. When you search OneSearch, if the library does not have the article in our collection, the system will also query Unpaywall, and may find and link to free sources for that article.
See the Unpaywall guide section on content type for examples and more details.
Unpaywall content is indexed in OneSearch (Everything @ Stan State).
Unpaywall will show up as a link to access the full-text in appropriate OneSearch records.
Sometimes the Unpaywall source will be a "pre-print" which does not include the final, full journal mark-up and layout. If you need the final version, it can be requested via Interlibrary Loan.
Unpaywall can sometimes link to an earlier working paper version of a study which eventually gets published as a journal article.
