ISBN Lookup/Duplicate Check Functions

ISBN Lookup/Duplicate Check Links are available in your Title Source 3 account. Simply use the Library Lookup to first check if a title you're considering is currently in your library's local catalog. This is a check against the library's catalog, not the previous titles you may have ordered through Title Source 3. The Duplicate Check link will check your ISBN against all other occurrences of that ISBN in your/all TS3 carts, depending upon your duplicate check profile.
