​The Lexis District of Columbia Advance Legislative Service, published quarterly, contains the latest acts of the Council of the District of Columbia. These convenient pamphlets contain a summary of act titles, the full text of the included acts, a cumulative table of the D.C. Code sections affected along with their D.C. Register citations, as well as notes and a cumulative Index so you can find what you need quickly and compare it to the previous law.

Along with the Advance Code Service and the semi-annual cumulative supplement to the Lexis District of Columbia Code, this is the best way to keep yourself informed on the changes to D.C. primary law.
