Links from non-WorldCat Record 856

Check this box to allow vendor-provided links in the Central index (any non-WorldCat database), which are mapped to the 856 field, to display as full text links in WorldCat Discovery. The links will inform the Access Online button in Discovery when configured.

Links from DOI

Users can access open content using DOI full text and open access links provided by Unpaywall. For more information see, https://unpaywall.org/faq. When enabled, DOIs will inform the Access Online action on search results, detailed records, and Course Reserves. DOIs are compared to Unpaywall data to ensure that only DOIs leading to open access content display. If a DOI is not present in Unpaywall, the DOI will not inform the Access Online button, but will continue to display in the Description of detailed records.

 Note:  If a user encounters a link from Unpaywall that does not lead to Open Access, report the link to team@impactstory.org.
