How does SWLCAT determine which collections are available for Interlibrary Loan?

SWLCAT determines which collections are available for Interlibrary Loan based on demand and policy guidelines. This approach ensures that the available materials align with the interests and needs of the library patrons, as well as adhere to the established policies governing interlibrary lending. By analyzing demand, SWLCAT can identify which resources are frequently requested and should be included in the lending program, effectively catering to user needs while ensuring compliance with policies that dictate what can be shared between libraries. This systematic approach contrasts with random selection methods or reliance solely on librarian recommendations, which may not reflect actual patron needs or preferences. Additionally, a yearly survey of patrons could aid in understanding preferences but does not dictate the availability of collections. Instead, it’s the combination of demand assessment and adherence to policy guidelines that forms the core of SWLCAT's interlibrary loan strategy.
