The National Survey of State Laws, by Richard Leiter (7th ed.) is now available as a database on Hein Online. For more than fifty topics, you get a synopsis of every state’s laws, presented as a table, with complete citations. Subjects run from family law to drug laws and minimum wage laws. You can customize the table to show only the states you are interested in, and also see the laws as they stood in 2008 and 2005. The print edition is on order.
Other handy sources of 50-state law summaries include the Subject Compilation of State Laws, which lists statute surveys that appear in law journals and legal treatises; Westlaw 50 State Statute Surveys, and LexisNexis 50 State Surveys: Statutes and Regulations.
