Some starting points:
- Cornell's Legal Information Institute(LLI) has a wealth of user-friendly information and browse/search interfaces including links to collections of: Federal Law (including my favorite interface for the U.S. Code of Laws) and State Law by topic and by jurisdiction/state.
- Library of Congress's (LOC) Law Library Reading Room offers a number of resources including a Guide to Law Online which provides descriptions and web links to free online information on government and law worldwide.
- Rominger's Legal Research Page provides lists of free online accessible: Federal Links (U.S. Code, Supreme Court, Federal Register, etc.), State Legal Resources (by state), Legal Resources, Legal Organizations, News On-line, Professional Directories, and various Non-Legal resources.
Many of the above web site offer links to two U.S. federal web sites:
* Library of Congress's Thomas: Legislative Information on the Internet has online copies of the text, status and summaries of U.S. federal Bills.
* The Office of the Law Revision Counsel publishes a searchable online version of the U.S. Code of Laws.
