State Agency Databases Project: Home


In every US State and the District of Columbia, agencies are creating databases of useful information - information on businesses, licensed professionals, plots of land, even dates of fish stocking. Some of this content is available on search engines, but much of it is part of the invisible web. Since July 2007, librarians and other government information specialists have been working on identifying and annotating these databases in one place. We've chased across fifty state web sites so you don't have to! ALA RUSA named this site one of its Best Free Reference Web Sites of 2012.

If a page below says "Available for adoption" and you are interested in taking it over, review the Volunteer Guide. If you can meet the requirements, please contact slrodgers at

Our project focuses on publicly searchable databases. If you are looking for underlying data, you might try the state data registry maintained at It is far from comprehensive but interesting to look through.
