Please note: This is a Sole Source Notification. Specifications include, but are not limited to: The Missouri Office of the Secretary of State (SOS) requires continued access to the suite of inter-related library products and services from the library bibliographic database and electronic services vendor, OCLC Online Computer Library dba OCLC Inc. OCLC provides the following services: WorldShare Metadata/OCLC Cataloging, WorldShare Interlibrary Loan, EZProxy, First Search/WorldCat Discovery Service, Dewey Decimal Classification publications, and WebDewey (collectively referred to as “OCLC Services”). OCLC is the only provider of all of the inter-related services that are needed by SOS. OCLC is the only source from which Missouri State Library may obtain the OCLC Services. Additionally, OCLC provides volume discounts for use of several products in concert, specifically WorldShare Interlibrary Loan and FirstSearch/WorldCat Discovery on behalf of Missouri public libraries. As a result, this represents a proprietary requirement that meets the criteria as a single feasible source under section 34.044, RSMo and the state is pursuing this acquisition via a single feasible source procurement.
