In May 2014, ProQuest LLC also operated businesses under the following names:
Eugene Power, a 1930 M.B.A. graduate of the University of Michigan, founded the company as University Microfilms in 1938, preserving works from the British Museum on microfilm. By June 1938, Power worked in two rented rooms from a downtown Ann Arbor funeral parlor, specializing in microphotography to preserve library collections. In his autobiography Edition of One, Power details the development of the company, including how University Microfilms assisted the OSS during World War II.This work mainly involved filming maps and European newspapers so they could be shipped back and forth overseas more cheaply and discreetly.
Power also noticed a niche market in dissertations publishing. Students were often forced to publish their own works in order to finish their doctoral degree. Dissertations could be published more cheaply as microfilm than as books. ProQuest still publishes so many dissertations that its Dissertations and Theses collection (formerly called Digital Dissertations) has been declared the official U.S. off-site repository of the Library of Congress.
The idea of universal adoption of microfilm publication of doctoral dissertations was furthered considerably by two articles researched and written by a then recent recipient of the doctorate in History at Stanford University. Vaughn Davis Bornet seized on the idea and published "Doctoral Dissertations and the Stream of Scholarship"and "Microfilm Publication of Doctoral Dissertations".
As the dissertations market grew, the company expanded into filming newspapers and periodicals. The company's main newspaper database is ProQuest Newsstand.
In 1962, Xerox acquired the company for 51,750 shares of Xerox common stock, worth about $7.9 million.Under Xerox's ownership, the name of the company changed several times, from University Microfilms to Xerox University Microfilms, to University Microfilms International, then shortened to UMI. In 1985 it was purchased from Xerox by Bell & Howell. In 1986, UMI acquired Data Courier, owner of ABI/INFORM, from the Bingham family.
In the 1980s, UMI began producing CD-ROMs that stored databases of periodicals abstracts and indexes. At a time when modem connections were slow and expensive, it was more efficient to mail database CD-ROMs regularly to subscribing libraries, who installed the discs on dedicated PCs. The ProQuest brand name was first used for databases on CD-ROM. An online service called ProQuest Direct was launched in 1995; its name was later shortened to just ProQuest.The bibliographic databases are mainly sold to schools, universities and libraries.
In 1998, the company announced the "Digital Vault Initiative", purported to include 5.5 billion images digitized from UMI microfilm, including some of the best existing copies of major newspapers dating back 100 to 150 years, and Early English books dating back to the 15th century. While work continues to digitize the contents of the microfilm vault, ProQuest is already providing navigation of 125 billion digital pages, including nearly 20 million pages of newspaper content dating from pre-Revolutionary War America.
In 1999, the company name changed to Bell & Howell Information and Learning, and then in 2001 to ProQuest Information and Learning; Bell & Howell renamed itself the ProQuest Company.
Also in 1999, the company acquired Chadwyck-Healey, a one-time microfilm publishing company that was one of the first to produce full-text CD-ROM databases. This acquisition gave Proquest ownership of a 100+ person publishing operation based in Cambridge, England and became the basis for a substantial overseas expansion.
During the 2000–2004 fiscal years, as well as the first three quarters of the 2005 fiscal year, ProQuest systematically overstated its net income. Cumulatively, pre-tax profits were overstated by 129.9 million dollars (or about 31 percent).In 2008, Voyager Learning Company and ProQuest's CFO (from the time of the earnings overstatements) settled SEC "charges without admitting or denying the allegations of the SEC's complaint".
In 2001 ProQuest acquired Norman Ross Publishing, a small New York based microfilm publisher.

Also in 2004, the company acquired Copley Publishing Group.
In 2006, ProQuest Company, then the parent company of ProQuest Information and Learning, sold it to Cambridge Information Group, owner of R. R. Bowker.From the time of this sale, this article follows the history of ProQuest Information and Learning, not ProQuest Company. (ProQuest Company subsequently renamed itself to Voyager Learning Company, and later became part of Cambium Learning Group. )

CIS produced one of the world's most exhaustive online collections of legislative content and highly respected statistical works, while UPA included deep historical content sets. The acquisition included digital products and an expansive microfilm vault that would leverage ProQuest's strength in conversion from film to searchable electronic formats.
