This is a sole source pre-solicitation notice for a subscription to the OCLC database for cataloging and interlibrary loan services, with the intent to award to OCLC, Inc. The justification is that OCLC is determined to be the only vendor capable of providing this specific, industry-standard service. The period of performance for the required services is from July 1, 2026, through June 30, 2027. While this is not a request for competitive proposals, firms believing they can meet the requirements may submit substantiating documentation to the point of contact. No budget or specific performance location is detailed in this notice.
