The Library of Congress intends to sole source a contract for the renewal of its subscription to the Raiser’s Edge NXT software, which is critical for its fundraising and event management operations. This procurement will encompass training, software upgrades, patches, troubleshooting, and hotline support, ensuring the Library maintains continuity in its operations. The justification for this sole-source acquisition highlights the proprietary nature of the software and the significant challenges associated with transitioning to an alternative system. The contract is expected to run from November 2024 to October 2028, with an estimated total value linked to multiple option periods. Interested parties can contact Kevin Barnes at kbarnes@loc.gov or 202-251-8024 for further information.
