ProQuest LLC is an Ann Arbor, Michigan-based global information-content and technology company that provides solutions, applications, and products for libraries. Its resources and tools support research and learning, publishing and dissemination, and the acquisition, management and discovery of library collections. From its founding as a producer of microfilm products and then as an electronic publisher, the company has grown through acquisitions. Today, the company provides tools for discovery and citation management and platforms that allow library users to discover, manage, use and share research gained from authoritative content. Total content, including dissertations and theses, ebooks, newspapers, periodicals, historical collections, governmental and cultural archives and other aggregated databases is estimated at over 125 billion digital pages. Content is accessed most commonly through library Internet gateways. The current chief executive officer is Kurt P. Sanford. ProQuest is part of Cambridge Information Group.
ProQuest was founded as a microfilm publisher. It began publishing doctoral dissertations in 1939, has published more than 3 million searchable dissertations and theses, and is designated as the offsite digital archive for the United States Library of Congress. The company's scholarly content includes dissertations and theses, primary source material, ebooks, scholarly journals, historical and current newspapers and periodicals, data sources, and other content of interest to researchers. These are made available through a variety of Web-based interfaces. A recent offering, ProQuest Video Preservation and Discovery Service, allows libraries to preserve and provide access to their proprietary audio and video collections.
ProQuest LLC also operates businesses under the following names:
Dialog is an online information service with more than 1.4 billion unique records curated for corporate, business and government researchers, with a focus on pharmaceutical, engineering and patent research.
EBL (Ebook Library), an ebook aggregator with a catalog of titles from academic publishers, serves academic, corporate and research libraries while supporting emerging collection development models such as patron-driven acquisition.
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. 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.
Xerox owned the company for a time in the 1970s and 1980s, and it was later bought by Bell & Howell. The name of the company changed several times in this period, from University Microfilms to Xerox University Microfilms, to University Microfilms International, then shortened to UMI.
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.
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.
In 2004, ProQuest Information and Learning acquired Seattle start-up Serials Solutions, a venture providing access management and search services for content hosted by other companies.
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.
In 2007, ProQuest Information and Learning was merged with CSA to form ProQuest CSA. Later that year it was renamed ProQuest LLC.
In 2008, ProQuest LLC acquired complete ownership of RefWorks, a web-based citation manager of which it had been part owner since 2001. RefWorks was merged with ProQuest's existing COS business to form RefWorks/COS.
In 2010, ProQuest acquired two properties from LexisNexis, Congressional Information Service (CIS) and University Publications of America (UPA). 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.
In 2013, ProQuest acquired Ebook Library (EBL), with plans to combine the strongest features of ebrary and EBL into a single, comprehensive e-book platform.
In 2014, ProQuest acquired Pi2 Solutions, a privately owned company specializing in Product Literature Database (PLD) systems for the biopharmaceutical industry. The company plans to align Pi2 with its ProQuest Dialog corporate information service.
