The Library of Congress published this Special Notice on April 21, 2026, announcing its intent to sole source a service contract to Gerstel, Inc. for comprehensive maintenance and support of a Gerstel MPS (MultiPurpose Sampler) automated sample handling system. The notice is issued under FAR Part 5.2 and FAR Part 6.2 to publicize the Library's determination that only one responsible source exists for this requirement. The contract action represents a continuation of service and maintenance support that has been in place since the initial five-year agreement began in FY21. This public notice serves as the sole announcement of the award intent, eliminating the need for a second posting after contract award. The due date for this special notice is May 4, 2026.
