Reference USA, the premier database for researching companies in the U.S. has now expanded to include companies and residents in Canada as well. More than 1.5 million Canadian businesses have been added to the 14 million U.S. businesses already available to search by line of business, geography, sales revenues, and more. This is a great resource for researching the competition or finding customers for your products and services. In addition, Reference USA has added physicians and dentists in the U.S. -- searchable by name, specialty and geographic area.

Your Dayton Metro Library card provides access to this and many other valuable databases. From any Internet computer, go to the library homepage, click on Research and Databases, then click on One Search and Research Databases. The databases are listed alphabetically.
