"Blue Sky Laws" is the collective name for the securities regulation statutes of the 50 states. These laws can be found in each state's codified statutes, administrative codes and cases.
The Blue Sky statutes, regulations and (summaries of) cases of all the states are compiled in CCH's Blue Sky Law Reporter. The Reporter is available in print as a multi-volume looseleaf and online through Lexis (CCH;CCHSEC), Westlaw (CCH-BSLR) and CCH's subscription-based Intelliconnect.
