The Department of Defense, through the Naval Research Laboratory (NRL), intends to award a sole source purchase order to Mary Ann Liebert Inc. for various publications, including titles such as "3D Printing and Additive Manufacturing," "Astrobiology," "Soft Robotics," and "The CRISPR Journal." This procurement is based on the determination that Mary Ann Liebert Inc. is the only responsible source capable of fulfilling the requirement, and it will utilize Simplified Acquisition Procedures under FAR Part 13.106-1(b) for purchases not exceeding $250,000. The publications are essential for supporting the NRL's research and development efforts in advanced scientific fields. Interested parties may submit their capabilities to respond to this requirement, but any competition must clearly demonstrate advantages to the Government. For further inquiries, interested vendors can contact Carrie Cawley at carrie.a.cawley.civ@us.navy.mil or Katrina Gallagher at katrina.t.gallagher.civ@us.navy.mil.
