By the end of the nineteenth century, the role of the librarian had expanded to include reference service, and it has been part of the profession since then. New technologies change the way we search for information and what we expect from reference service. With the introduction of the computer and the Internet, libraries expanded the role of reference beyond the use of the mail, telephone, or the fax machine. Today, librarians not only help patrons at the reference desk but also in cyberspace.
