For general reference librarians and managers in academic libraries, Kellam (data services and government librarian, U. of North Carolina at Greensboro) details how to set up and sustain numeric data services. Focusing on social science data sources, she explains key terms and background; different types of data compilation; the creation and growth of data services; techniques for marketing; virtual and physical presences like Web 2.0; assessing data services; patron interactions, including the reference interview and using statistics and numeric sources in instruction; experiences of data librarians from the US and other countries; and three current areas of data librarianship: data visualization, preservation, and citation. One chapter is by Katharin Peter (social sciences data librarian, U. of Southern California), who outlines major data vendors for use in acquisitions and search strategies for finding data, as well as international, US, Canadian, and British sources.
