You can find cases in a variety of different places.

Print Reporters

In the olden golden days cases were only available in books called reporters.

Most states designate an official case law reporter which is published by the state government or a private publisher. The official reporter for Maine is the Atlantic Reporter, part of the West National Reporter System. The other reporter is West's Maine Reporter. Both reporters contain all published Maine Supreme Judicial Court cases. 

Online Sources

Cases are also available online from the United States and Maine's judicial branch websites, from commercial services (Westlaw, LexisNexis, Bloomberg Law, LoisLaw, Fastcase, etc.) and from free websites (Google Scholar, Findlaw, LexisONE, Legal Information Institute, court sites, etc.). Beware, some of these sources include unpublished cases that cannot be cited as precedent!

The National Reporter System is the combined case law reporter sets published by West Publishing that includes all (published) state and federal cases.
