Now in paperback with answer key included. The new third edition of this textbook includes questions that may be answered from electronic sources, such as the Internet, WILSONLINE, DIALOG, ORBIT, and various CD-ROMs, in addition to reference works in print formats. The work is designed to teach students in library and information science, as well as college and secondary-school students in library orientation and bibliographical instruction programs, to use reference works to locate data by providing experience with such tools. Chapters are based on types of reference works in electronic and print formats: encyclopedias, yearbooks, sources of statistics, biographical works, bibliographies, dictionaries, handbooks, indexes to periodicals, directories, and keys to government publications. Each chapter is subdivided into three sections: the first includes interviews that have taken place in public, academic, school, and special libraries; the second lists questions that can be answered from the sources listed in the third section.
