Lexis and Westlaw - Both include the state and federal criminal law statutes in their topical databases and are particularly useful for identifying new or amended statutes.
Each section is identified by its corresponding public law number and the date it became effective.
Both services include the electronic versions of U.S.C.S. (LEXIS) and U.S.C.A. (WESTLAW), as well as all state statutes, which contain case annotations.
If your paper discusses some aspect of a federal statute, you may wish to research its legislative history to determine the intent underlying its enactment. To do so, you may want to review such documents as congressional committee reports, committee hearings, and congressional floor debates.
See Law Library Guide to Federal Legislative History Research for information regarding specific legislative history documents.
When beginning, first check our catalog to see if we have the legislation you need at the law library.
If we do not have what you need or you are not entirely sure where to start looking, spend a few moments examining the Foreign Law Guide. This helpful research tool provides legal research information for numerous countries. Specifically, for each country, the guide provides an Introduction (legal system, legal history, legislation, and judicial system), Major Publications (major codes, official gazette, compilations or official codifications, session laws, court reports, and Internet sources), and Subject Arrangement (alpha order of subjects with references to specific laws, acts, codes in the official sources, and to English translation, if available).
You also might find it helpful to consult an online research guide on the relevant country for further instruction and detail.
Lastly, I've included some useful websites below (also see the list under the "Case Information" heading above, which includes databases with legislation for other countries such as China and Israel).
