Working conditions can vary greatly between libraries, depending on the size, location and type of library. In Western Australia, there are several hundred public libraries located throughout the State, in both regional and metropolitan areas. There are also a large number of university, government and business libraries, though not all libraries will necessarily employ library assistants. The majority of library assistants in Western Australia work in the Perth metropolitan area. Evening and weekend work may be required, however this may vary depending on the size and location of the library. Library assistants may spend long periods standing.

Library assistants use computers to record the lending and return of library materials, to access information stored in electronic databases and journals. They will also need to be familiar with a number of specialised electronic databases and catalogues used to manage and locate records and information both in their own library, and in some cases, at other locations. Trolleys are often used to transport books around the library for shelving, and ladders may be used to reach high shelves.
