New content on lexis.com® to provide legal professionals with enhanced information resources for evaluating how new legislation and regulations will impact existing law

June 20, 2007 — New York, NY, June 20, 2007 - LexisNexis, the leading provider of information and services solutions for the legal profession, today announced that two highly regarded online resources for analyzing the impact of new legislation and regulations on existing law will now be available only to users of lexis.com.

The powerful new content additions tolexis.com are the result of an exclusive agreement between LexisNexis and DataStream Content Solutions, parent company to Potomac Publishing.

Lexis.com users range from the largest national corporate law departments and global law firms to individual attorneys in private practice.  Beginning June 23, these customers will have exclusive access to Potomac’s two online databases, Legislative Impact® and Regulatory Impact™, to help determine how new legislation and regulations will impact existing law.

“The Potomac Publishing Company databases enhance the productivity of attorneys by helping them identify and understand legislative interactions quickly and simply,” said Allan McLaughlin, senior vice president of research solutions for LexisNexis.

“We’re committed to building on our market position as the premier provider of authoritative online research content for the legal profession.  The exclusive availability of these two Potomac Publishing databases via lexis.com is a primary example of the LexisNexis commitment to offer attorneys the best, most relevant legal content available as part of our Total Practice Solutions strategy.”

Legislative Impact tracks how, where and when federal laws interact with one another.  In today’s increasingly complex statutory environment, this can be a Herculean task for even the most capable attorney or paralegal.  Legislative Impact delivers this information while also assessing the potential impact of bills currently before Congress to give attorneys a heads-up of what will be next over the legislative horizon.  Together with its counterpart, Regulatory Impact, which performs the same authoritative cross-referencing of federal regulations, the two databases combine to form a powerful suite of legal intelligence products that effectively complement the complete range of lexis.com services.

“Potomac Publishing offers innovative technological solutions, applied to legal data, in order to make research easier,” states Edward Schulke, chief information architect for Potomac Publishing.  “We are excited by the possibilities of combining our XML-based innovations with the depth and breadth of legal information from LexisNexis in order to revolutionize legal research.”
