This training manual was written for student reference assistants to teach them about the Monterey County Free Library (California) and about libraries in general. It introduces library nomenclature (e.g., automated system, interlibrary loan, and MLS), describes requirements of the reference assistant position, and provides information on how to be successful in the position. Specific sections discuss: (1) aspects of reference service--e.g., determining what patrons are really asking and conducting a reference interview, and (2) the characteristics of five useful reference tools: the card catalog, encyclopedias, Reader's Guide, Magazine Index, and almanacs. Each section has a subsection called "On Your Own," which provides practice exercises and space for the trainee's own notes. An answer page is also included. (SD)
