The Resolver Sources can be modified to control the display of resolver links by the following categories:

 

• Ovid Knowledge Base: The default Ovid Discovery Link Resolver source
• Library Catalogue: Links to items included in the library catalogue (if applicable)
• Institutional Print Holdings: Checks for items activated as print holdings
• Full Text From Publication: Items with Full Text access from activated holdings
• Open Access from Ovid Index: Items with Open Access full-text links in Ovid index
• Unpaywall: Items with Open Access availability in the Unpaywall databases

 

For example, if there is a requirement to only provide full-text links for subscribed holdings, and not for Open Access publications, the resolver links for Open Access publications could be removed by disabling the Open Access from Ovid index source.
