Have you ever wondered what website a reference librarian went to first to answer your question? Often, it's Zimmerman's. Zimmerman's Research Guide has short entries that describe the top resources on many subjects. It includes many links and lists the appropriate Lexis and Westlaw databases. It's easy to see why many librarians use this self-described "online encyclopedia for legal researchers."
