Directories Mission

We believe directories are only useful if they are comprehensive, accurate and timely. That’s why we offer every marketing research firm and branch location a free basic listing in our comprehensive Researcher SourceBook™ - the worldwide directory of marketing research product and service providers. We also list qualifying research firms in our specialty facility and service directories at no charge. Because our directories are the most complete, they are also the most used in the industry. In fact more than 43,000 research professionals rely on Quirk’s Marketing Research Review each month and another 1 million+ visit


Each year we publish the Researcher SourceBook™ and nine directories of research facilities and special research services. Each directory is published in print in a different month mailed to our 17,000+ subscribers as part of their magazine subscription. The information for each directory is also made available on our Web site.

Researcher SourceBook™

The most comprehensive directory of research providers from around the world, with over 7,100 listings in more than 100 countries.

Directories of Special Research Services and Facilities
