CONCORD, Mass.--(BUSINESS WIRE)--June 20, 2005-- OneSource® Information Services, Inc. a Donnelley Group company of infoUSA (NASDAQ:IUSA - News ), today announced major enhancements to its flagship business information product, Business Browser(SM). The new version of US Business Browser adds in-depth profiles on over 160,000 private companies and expands core coverage from 300,000 to 600,000 United States and Canadian companies. In addition, OneSource is introducing two new products: The Small Company Spectrum, which provides basic information on over 13 million additional companies; and a new Credit Insights module that provides risk assessment indicators for all 13 million companies.

The broad range of enhancements is made possible largely by OneSource''s relationship with their new corporate parent infoUSA, the nation''s premier compiler of business-to-business data on North American companies. As an experienced integrator of business content from providers around the world, OneSource is capitalizing on infoUSA data and research capabilities to meet and exceed the needs of its customers.

"With the launch of this new version of US Business Browser and our new credit and small business products, OneSource has addressed several critical customer demands," said Yvonne Cekel, President of OneSource Information Services, Inc. "Once again, we are leading the market with business information solutions to help our customers achieve sales and marketing success."

Strategic selling to over 160,000 private companies

Private companies are essential prospects for many organizations, and obtaining accurate information on this group of businesses is a challenge for most business professionals. OneSource customers can now be more informed and strategic in their marketing and sales efforts with access to key information on more than 160,000 companies--the most comprehensive collection of private company profiles available. This in-depth information includes business descriptions and executive contacts, delivering a deeper level of information and the highest level of accuracy.

"Our most recently published Hot Topics study on Salesforce Performance Solutions identifies a big private company information gap," said Chuck Richard, VP and Lead Analyst at research and advisory firm Outsell, Inc. "Clients regularly tell us they''ve hit dead-ends looking for comprehensive and accurate sources of private company information. The market is hungry for meaningful enhancements to information on private and small businesses such as those offered in the products announced today by OneSource."

Small Company Spectrum Product: Find, understand and sell to small businesses

Also new from OneSource is the Small Company Spectrum product, which delivers a universe of 13 million small businesses featuring details on location, company size, industry, key contacts and more. The Small Company Spectrum product when used with Business Browser provides customers with business information on the broadest range of North American companies available, spanning businesses from the smallest proprietorship to the largest enterprise. As a result, it allows sales and marketing professionals to be more knowledgeable when approaching potential customers by giving them valuable insight. Small Company Spectrum is ideal for companies that provide broad-based business services such as telecommunication equipment, loans, payroll services, cash management, insurance, office products, healthcare products and more.

Credit Insights: Improve selling time and close rates

Gauging a prospect''s ability to pay during the sales and prospecting process is critical before entering into new business relationships with unfamiliar companies. Credit Insights, a new add-on module to Business Browser, provides modeled credit ratings and recommended credit limits for up to 13 million companies in the U.S. and Canada. Credit scoring is based on industry volatility, size of a company, and the length of time in business. Credit Insights is ideal for sales reps developing preferred prospecting lists, enabling them to focus on the most promising candidates.

Pricing and Availability

The enhanced version of Business Browser will come at no additional cost to customers. The Credit Insights and Small Company Spectrum are offered individually, at $5000 per year for five users or at $84 per month per user. OneSource will begin rolling out this new version of Business Browser and its new products beginning in July.
