The U.S. Geological Survey Library awarded a purchase order to ProQuest LLC for a subscription to ProQuest Dissertations & Theses Global on September 24, 2026, with a ceiling value of $87,003.28. The order covers one base year (September 24, 2026 through September 23, 2027) plus four option years extending through September 23, 2031. Place of performance is Ann Arbor, Michigan. USGS requires access to over six million metadata records for dissertations and theses from more than 3,600 universities across over 75 countries, with four million available in full text online and 300,000 new records added annually. USGS justified sole-source award on PQDT Global's unique institutional integration with Web of Science, which USGS already licenses through Clarivate, the parent company of ProQuest, asserting no competing commercial service provides equivalent coverage and international reach with seamless platform integration.
