Massachusetts Case Finding Tools

A Massachusetts-specific secondary source such as Massachusetts Practice or Massachusetts Jurisprudence will provide an overview of the law, and citations to the most important cases. The American Law Reports (A.L.R.), which cover state and federal jurisdictions, are also an important tool for case law research.

Once you have an overview of your topic, find cases by subject using West's Massachusetts Digest and/or full-text databases.

Always remember to update your research by using a citator.

American Law Reports (A.L.R.) contain annotations that cover very specific areas of law and provide citations to case law in all jurisdictions. This will be very helpful if you are researching an issue that has not been decided by the Massachusetts courts. For a primer on using the A.L.R., see Finding Cases Using the American Law Reports.
