LexisNexis

Summary
LexisNexis is a part of the RELX corporation (formerly Reed Elsevier) that sells data analytics products and various databases that are accessed through online portals, including portals for computer-assisted legal research (CALR), newspaper search, and consumer information. During the 1970s, LexisNexis began to make legal and journalistic documents more accessible electronically. the company had the world's largest electronic database for legal and public-records–related information. LexisNexis is owned by RELX (formerly known as Reed Elsevier). According to Trudi Bellardo Hahn and Charles P. Bourne, LexisNexis (originally founded as LEXIS) is historically significant because it was the first of the early information services to both envision and actually bring about a future in which large populations of end users would directly interact with computer databases, rather than going through professional intermediaries like librarians. The developers of several other early information services in the 1970s harbored similar ambitions (e.g., OCLC's WorldCat), but met with financial, structural, and technological constraints and were forced to retreat to the professional intermediary model until the early 1990s. The LexisNexis story begins in western Pennsylvania in 1956, when attorney John Horty began to explore the use of CALR technology in support of his work on comparative hospital law at the University of Pittsburgh Health Law Center. Horty was surprised to discover the extent to which the laws governing hospital administration varied from one state to another across the United States and began building a computer database to help him keep track of it all. In 1965, Horty's work inspired the Ohio State Bar Association (OSBA) to independently develop its own CALR system, Ohio Bar Automated Research (OBAR). In 1967, the OSBA signed a contract with Data Corporation, a local defense contractor, to build OBAR based on the OSBA's written specifications.
