Book excerpt: Guided by the editorial support of colleagues in the Library and Information Technology Association (LITA), author Tom Wilson, head of systems at University of Houston Libraries, demystifies this critical specialty. In clear nontechnical language, Wilson answers the befuddling question, What is a systems librarian? Wilson lays no claim to the one right answer. Instead, The Systems Librarian: Designing Roles, Defining Skills will lead you in formulating your own answer, which is the first step to making sound decisions.
