LexisNexis

Although ranked as one of the worst places to work in America, LexisNexis has one of the best databases available at the library to students. The service is a paid service (usually by the university) and allows access to over 30 terabytes of information on their mainframe. I have used LexisNexis mostly for legal research that I had to do during my law internship. It is very easy to look up articles - especially when you narrow it down by date and location. Law offices/institution almost always have a LexisNexis subscription.

The service is divided into two parts - Lexis and Nexis. Lexis is the service's database of briefs, motions, statues, opinions, and legal cases in history (mostly the US). It is very important for law institution to have this service to be able to do legal research for their cases. One of the things they teach you in law school is how to effectively use Lexis. Nexis, on the other hand, has content such as global news, intelligence, reference, public records, and other legal materials. With a collection of over 20,000 sources that are always being updated and increased, it is difficult not to find something you are looking for on LexisNexis.
