There are two commonly-used encyclopedias, American Jurisprudence (AmJur) and Corpus Juris Secundum (CJS), that are good sources of general information on a particular subject. Legal encylopedias contain general discussions of legal issues with citations to case law across jurisdictions. Both sets are located in the library on the 2nd floor near the Federal and State Reporters. They can also be accessed on Westlaw and Lexis.

AmJur has a comprehensive section on Copyright and Literary Property. It addresses the scope and subject matter of copyright protection, notice and registration, duration and renewal, as well as civil and criminal liability for infringement.
Some other sections of interest may include:
