If your professional quest requires serious research, you might try ProQuest. The company provides access to and navigation of more than 125 billion digital pages of scholarly content from some 9,000 titles. Holdings include a digital newspaper archive, periodical databases, and a dissertation collection on editorial areas such as arts and literature, science, technology, and medicine. ProQuest subsidiary Dialog provides digital research services and information. The company can trace its roots to 1938, when Eugene Power founded University Microfilms. ProQuest is now owned by Cambridge Information Group (CIG), a group of information services and publishing companies and educational institutions.
In addition to the ProQuest brand, the company also releases products under brands such as UMI (microform and print reference products), Chadwyck-Healey (electronic and microform resources), and SIRS (information on key curricula subjects). In 2010 the company launched a new search platform that organizes all of its content into one unified search experience for end users.
In other efforts at product enhancement, in 2010 ProQuest launched its ProQuest Dialog offering. The company had acquired Dialog from Thomson Reuters two years earlier in order to expand beyond the academic library arena. The purchase gave ProQuest a boost in the corporate market, strengthening its customer base and adding content in the fields of health, pharmaceuticals, and intellectual property. However, it took ProQuest a couple of years to begin fully integrating Dialog's content. With the launch of ProQuest Dialog, the company offers a major upgrade and redesign to the service, including advanced tools for search results management.
The company experienced more growth in 2010 when it acquired the London School of Economics' classic International Bibliography of the Social Sciences (IBSS). The addition bolstered its academic research capabilities in the social studies arena. The funding for IBSS was about to end, and the acquisition by ProQuest assured the research database's future. Then, in 2011 ProQuest expanded its digital offerings with the acquisition of ebrary, a Palo Alto, California-based provider of e-content services and technology. With ebrary's capabilities, ProQuest users can search across multiple formats, including e-books and video content.
CIG formed the current iteration of the company when it purchased the Information and Learning division of Voyager Learning Company (formerly called ProQuest, and before that Bell & Howell Information and Learning) in 2007 for approximately $222 million. CIG then merged the acquired business with information provider Cambridge Scientific Abstracts (CSA). – less
