Sole-Source Justification for My Talking Books (RealSAM) Dialog Licenses
Solicitation # 2027-NLS-0066
The Library of Congress intends to award a sole-source, firm-fixed-price, indefinite-delivery, indefinite-quantity contract to RealSAM Inc./RealThing.ai for a five-year period to provide up to 5,000 new RealSAM dialog licenses and ongoing technical support for 5,000 legacy licenses already in use. The work will be performed at the contractor’s facilities and includes comprehensive support such as system maintenance, documentation, and compliance with federal regulations. This procurement exceeds both the simplified acquisition threshold and public-notice threshold, necessitating this public synopsis in accordance with the Federal Acquisition Regulation. The contract will support the National Library Service for the Blind and Print-Disabled in delivering accessible services to its users through the RealSAM dialog platform. No competitive bidding will be conducted, as this is a sole-source acquisition justified under existing procurement authority, and this notice serves as the only public announcement required under FAR 5.2. The Justification and Approval for sole-source selection has been publicly posted in advance of award, eliminating the need for a post-award disclosure. Potential vendors may submit capability statements for review, but the Library is under no obligation to modify its procurement approach unless compelling evidence is presented. The solicitation number is 2027-NLS-0066, the NAICS code is 541511, and responses are due by August 21, 2026. Point of contact for inquiries is James Robinson at the Library of Congress.

NISC Enterprise Support Tasking (NEST)
Solicitation # 693KA9-26-R-00003
The NISC Enterprise Support Tasking (NEST) solicitation 693KA9-26-R-00003 is a set-aside for Women-Owned Small Business (WOSB) concerns to provide operations, maintenance, and technical support for the Federal Aviation Administration's NIMS and CMIS systems. The contractor will manage the task order and financial management lifecycles, ensuring seamless integration with FAA financial systems including PRISM and Delphi. A critical component of the scope is the transition from the NISC IV contract to the NISC V contract, requiring the vendor to act as a Subject Matter Expert for the design, development, testing, and deployment of new software and architecture to support NISC V while maintaining the NIMS system for NISC IV closeout. The contract is structured as a firm fixed price agreement featuring a 12-month base period and four 12-month option periods. Key responsibilities include providing quality assurance, maintaining security certifications and Authority to Operate (ATO) compliance, and delivering comprehensive system documentation and monthly status reports. Performance is based on adherence to FAA IT standards, the Enterprise Risk Management Framework, and the Enterprise Architecture Framework. The procurement process includes a live NIMS demonstration on September 9, 2026, with a final response deadline of October 15, 2026. The selected vendor must also provide transition support to any subsequent vendor at the conclusion of the contract.
