The ABA Journal reports that LexisNexis and Microsoft reached an agreement to integrate Lexis legal research in to Microsoft Office 2007 and the soon-to-be-released Office 2010.  According to the ABA article:

Lexis will now be integrated into Microsoft Office products, allowing users to do legal and general research directly while working in Microsoft Word, Outlook and SharePoint. Users, who must have a Lexis subscription, need only click on a Lexis tab in the ribbon of utilities available in Microsoft Office 2007 and the forthcoming 2010 version to start researching, Shepardizing cases or even gathering information from Bing or Google search engines. There is no need to navigate separately to the Web and log on to Lexis or a search engine.
