LexisNexis Launches New Search Capabilities for BlackBerry

Simplified Search Helps Business Professionals Get Critical Information Anytime, Anyplace

This new development follows on the heels of the April 27th release announcing that BlackBerry users can receive current news on predefined topics of interest delivered via LexisNexis® Publisher.

"LexisNexis is taking a significant step forward, which will open up new opportunities for business professionals who are looking for quicker and more convenient ways to access critical and industry-specific information while in transit," said David Worlock, Chairman of EPS, a research and consultancy firm for the information industry. "With the widespread use of mobile devices, this has become a space in which we shall all have to play."

"Professionals today work from everywhere-the office, the home, the car, and the airport," said Elizabeth Rector, senior vice president, Corporate and Federal Markets, LexisNexis. "We've created a simplified LexisNexis search that is easy and convenient to use on BlackBerry handhelds. Understanding the difference between a customer's needs while using BlackBerry and their needs when using PCs is critical to helping them do business anywhere."
