Designed for use in a post-masters level course in library science, this model presents background information about the hypothetical library which is the context for the role-playing and in-basket exercises of a governmental library simulation. An organization chart, operations manual, annual report, and other documents serve to convey information to students about the library in which they will be making decisions and solving problems. Pedagogical considerations rather than strict realism determine the design of the documents; they resemble formats used by government agencies, but some have been simplified for value in teaching or ease in use.
