The Library of Congress in conjunction with Harvard University and the University of Pennsylvania (Solicitors), currently use a proprietary Library Archival System (LAS) to inventory and track the location of the analog, i.e., physical, general collection items. Information gathered through this RFI may be used for a possible future Library requirement to implement and migrate to a new library inventory management system to replace the existing proprietary system (LAS).
The RFI has much more info including a link to this document that lists requirements the three organizations want in a new system.
