Doing Consumer Research: A Resource Guide

Subscription Sources

Business intelligence and consumer research can be costly, and many publishers or firms who collect and analyze consumer data charge for access to their reports. On this page are links to content that the Library of Congress subscribes to, which is available to researchers on-site. We've also included links to publishers for which we do not subscribe at the bottom of this page. Other institutions may have access to this content, or you may be able to read some report summaries, press releases or blogs for free by visiting their websites.

Subscription Databases

The subscription resources below marked with a padlock  are available to researchers on-site at the Library of Congress. If you are unable to visit the Library, you may be able to access these resources through your local public or academic library.


The following are sources primarily from market research firms, which require a purchase or subscription to access. While the Library of Congress does not endorse any specific company, some of these marketing firms include research and other sources of information and insight into the particular target markets that may be useful to researchers. It should, however, be noted that much of their information may be limited to members or subscribers. Some of these offer previews or a few select reports free of charge; they also may summarize findings in their press releases, blogs, or other other written content on their websites. For additional sources, see the Internet Sources page of this guide.
