ProQuest
American information company

ProQuest LLC is an Ann Arbor, Michigan-based global information-content and technology company, founded in 1938 as University Microfilms by Eugene Power.
ProQuest is known for its applications and information services for libraries, providing access to dissertations, theses, ebooks, newspapers, periodicals, historical collections, governmental archives, cultural archives, and other aggregated databases. This content was estimated to be around 125 billion digital pages.
The company began operations as a producer of microfilm products, subsequently shifting to electronic publishing, and later grew through acquisitions. On December 1, 2021, Clarivate bought ProQuest from Cambridge Information Group for $5.3 billion in what was described as a "huge deal in the library and information publishing world". Clarivate said that the operational concept behind the acquisition was integrating ProQuest's products and applications with Web of Science.

Begin with the source’s own compact description: “ProQuest” is american information company. The dossier treats that line as a proposition to test through ProQuest, American and information, not as a finished interpretation.
Why this record matters
The phrase “american information company” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Chronology, provenance and viewpoint should be read together before a broad social or political interpretation is accepted. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q2111400. VIAF identifies the subject as 143290139. The Library of Congress control number is n2007068018. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1938, 2021 and 1939.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
