EAGAN, Minn., March 29 /PRNewswire/ -- Westlaw(R) now provides the industry's most complete and integrated tool for statutes research. West, a Thomson business (NYSE: TOC; Toronto), today announced that ResultsPlus, the powerful research assistance feature available only on Westlaw, has been expanded to statutes searches. This new feature recommends additional relevant information resources, helping legal professionals quickly develop a thorough understanding of the issues they are researching. "ResultsPlus pointed me to a helpful key number even when the search I ran didn't find any documents," said Heather Heath of Hughes, Watters, Askanase, LLP, in Houston. ResultsPlus, introduced to case law researchers in June 2003, points legal professionals to relevant articles from American Law Reports (ALR(R)) and American Jurisprudence (Am Jur(R)), and provides recommended key number queries to enhance the accuracy of research. In 2004, West also added treatises as additional sources of information in ResultsPlus. Currently five treatises are available on ResultsPlus -- American Jurisprudence Proof of Facts, American Jurisprudence Trials, Norton Bankruptcy Law and Practice 2d, Immigration Law Service and Employment Coordinator -- and 15 more will be added in April. Each of these additional sources gives legal professionals the assurance that their research and understanding of the legal issues involved in their case is complete. "Expanding ResultsPlus to include statutes searching further demonstrates the superiority of statutes research on Westlaw," said Mike Dahn, director, Technology Product Development, West. "The combination of ResultsPlus with StatutesPlus, our market-leading tool for online statutes research, provides researchers with the best methods to quickly home in on the essence of a statutory issue. The result is more thorough research accomplished in less time." ResultsPlus relies on information research technologies developed by West's technology engineers. These technologies were originally developed to assist West's attorney-editors in classifying legal documents to the more than 100,000 topics and categories of the West Key Number System(R). This CaRE technology (Categorization and Routing Engine) uses patent-pending processes to analyze and understand the information characteristics of documents. ResultsPlus uses information generated by these unique processes to develop highly sophisticated queries that automatically are run against relevant analytical materials. For legal professionals, this means search results that reflect the context of a broader base of on-point primary and analytical law content.
