According to Martin (1996), the majority of librarians in Britain prefer to be known as either a “liaison librarian” or a “subject librarian”.  They believe that a subject specialist denotes that one has serious subject knowledge and qualifications, whereas a subject librarian is a professional librarian who happens to look after a particular subject.  At the University of Botswana Library (UBL), the term “library liaison” is used interchangeably with the term “subject librarian” (Martin, 1996).
