LexisNexis, a member of Reed Elsevier Group, does business in more than 100 countries with approximately 13,000 employees worldwide. The Lexis Service, one of the first commercial, full-text legal information services, began in 1973 to assist legal practitioners with researching law more efficiently. In 1979, Nexis, the companion news and business information service, was launched to offer recent and archival news and financial information. In addition to its flagship Web-based Lexis and Nexis research services, the company includes several legal publishers, such as Martindale-Hubbell, Matthew Bender, Butterworths, Les Editions du Juris Classeur, Abeledo-Perrot and Orac. LexisNexis provides information to legal, corporate, government and academic markets and publishes legal, tax and regulatory information through online, hardcopy print and compact disc formats. In 2004, the company acquired Interface Software, an Illinois-based organization. LexisNexis is headquartered in Miamisburg, Ohio.
