District of Columbia Research Guide


This research guide was created to facilitate your research of the laws of the District of Columbia. The law making process, sources of statutory law, rules and regulations are outlined. Links are also provided to resources for finding case law, court opinions, and secondary sources.

Sources cited are the print and electronic resources available in the Mason Law Library. It is useful to begin your search in the library's catalog, the gateway to our collections, as well as those of the Washington Research Library Consortium (WRLC). Call number links have been provided to facilitate your access to the resources.

In addition to commercial and other proprietary databases, the guide will highlight free, authoritative online resources available for District of Columbia legal research.

If you have further questions, please email us at,  and our team of helpful librarians will be happy to assist you.
