From the legal-ethics chapter:
American Legal Ethics Library. From Cornell’s Legal Information Institute, this digital library contains the full text of the codes or rules of professional conduct for most U.S. states, as well as the ABA’s model code. Some are in hypertext format, others are included through links to state bar or court sites. In addition, major law firms are contributing narratives on professional conduct requirements in their respective states. Materials are organized by both state and topic, and all are fully searchable. The narratives cover Arizona, Arkansas, California, Colorado, Connecticut, the District of Columbia, Florida, Illinois, Louisiana, Maryland, Michigan, New Jersey, New York, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina and Texas, with other states to be added. The library’s materials are organized both by state and topic, and all are fully searchable. Each element of the library is linked to the rest of the collection in multiple ways, permitting a user to track a specific issue or point from code to commentary in a single jurisdiction and to track the same question in materials from other jurisdictions.
