Librarians are experts in the contents and arrangement of their collections, as well as how information is organized outside the library. Library users are encouraged not to be shy about asking a reference librarian for help. Even though most librarians stay busy when not serving a patron, their primary duty when they are at the desk is to assist library users. Library users can consult the staff at the reference desk for help in finding information. The latest information available about the sources evaluated has been covered in detail. Information about the use of technology in their publication, storing and retrieval of online databases is also given.
