The MARS Best of Free Reference Web Sites is an annual series initiated to recognize outstanding reference sites on the World Wide Web. MARS is the Machine-Assisted Reference Section (MARS) of the Reference and User Services Association (RUSA) in the American Library Association.

"Since the Web is a changing world, readers should note that these Web sites were as annotated on the date the member reviewed the site. Reviewing previous lists is not part of the charge of the Committee (formerly the Task Force on the Best of Free Reference Web Sites). However, we will make note of updated links, or other very substantial changes (such as a conversion from free to fee-based), if they are brought to our attention." RUSA Quarterly Fall 2001.

The ARDA is one of 30 sites selected as a MARS Best of Free Reference Web Sites of 2010.
