Organization
Libraries have materials arranged in a specified order according to a library classification system, so that items may be located quickly and collections may be browsed efficiently. Some libraries have additional galleries beyond the public ones, where reference materials are stored. These reference stacks may be open to selected members of the public. Others require patrons to submit a "stack request," which is a request for an assistant to retrieve the material from the closed stacks. A list of closed stack libraries is being aggregated on Wikipedia.
Larger libraries are often broken down into departments staffed by both paraprofessionals and professional librarians.
- Circulation (or Access Services) - Handles user accounts and the loaning/returning and shelving of materials.
