The Resolver Sources can be modified to control the display of resolver links by the following categories:
- TDNet Knowledge Base: The default TDNet Discover 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 TDNet Index: Items with Open Access full-text links in TDNet 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 TDNet index source.
