(Dialog, A Thomson Corporation business, Cary, NC, www.dialog.com). The first commercial online information retrieval system, created by Roger Summit in 1967 and launched as a service in 1972. For years, DIALOG has offered the largest single collection of information available online, claiming over 900 databases in areas such as business, science, finance and law. Searching is free, but there are fees for viewing the results. Access is available via the Web or by separate dial-up numbers as was the norm before the Internet became popular. DIALOG's searchable content is considered to be part of the deep Web.

Dialog is an online information service owned by ProQuest, who acquired it from Thomson Reuters in mid-2008.[1][2]
Dialog was one of the predecessors of the World Wide Web as a provider of information, though not in form.[3][4] The earliest form of the Dialog system was completed in 1966 under the direction of Roger K. Summit.[5] According to its literature,[6] it was "the world's first online information retrieval system to be used globally with materially significant databases". In the 1980s, a low-priced dial-up version of a subset of Dialog was marketed to individual users as Knowledge Index.[7] This subset included INSPEC, MathSciNet, over 200 other bibliographic and reference databases, as well as third-party retrieval vendors who would go to physical libraries to copy materials for a fee and send it to the service subscriber.
