IDS Project Logo

A unified community of trust and support
built around a critical and clearly understood purpose
effective resource sharing.

IDS Project's CrossLink is a middleware server-based solution that allows for discovery and availability lookups across multiple cataloging systems and provides a connection between the borrowing and lending libraries’ resource sharing systems, regardless of which types they are.

This brokering system will allow libraries that have become siloed due to cost cutting and reduction in use of resource sharing systems to maintain services to their patrons while sharing their materials with other libraries.

Vision of CrossLink

  • Improve the efficiency and lower the cost of resource sharing 
  • Promote interoperability between different systems
  • Promote technology that will enable libraries to pursue consortial resource sharing while having flexibility to implement local library ILL workflows in the way that suits them best
  • Leverage the ISO18626 (ISO ILL standard) functionality which is increasingly becoming available in LSPs and resource sharing management systems
