Specifications include, but are not limited to: The State intends to secure a contract for a remotely hosted Software as a Service (SaaS) application to provide an online statewide library union catalog, which is a combined library catalog describing the collections of participating libraries, Machine Readable Cataloging (MARC) system, interlibrary loan system, and search portal. The system will be used by 300 Tennessee public libraries to access statewide holdings and records from Z39.50 targets, which are an industry standard client/server protocol for the intent of accessing bibliographic records from the participating library from the Union catalog, share resources, catalog library materials and search database resources. Other libraries will be allowed to either upload their collections to the catalog or provide their catalog as a Z39.50 target for interlibrary loan purposes.
