Q. Which search engines are the best to use to find legal articles or law related works?

LexisNexis Academic is probably the best place to start for legal articles and cases.

You can see a list of other databases used for legal research, by clicking on  DATABASES in the blue search box on the library homepage (see link below), then LAW in the search box and you will retrieve all the databases with content related to Law.

See link below to access the Government Documents and Information subject guide, this may be useful for you as well.  It includes contact information for the librarian who covers this subject. You can get in touch with her if you need further assistance.
