Young Brunette Girl Posing On The Floor In The Library

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.
- Collection Development - Orders materials and maintains materials budgets.
- Reference - Staffs a reference desk answering user questions (using structured reference interviews), instructing users, and developing library programming. Reference may be further broken down by user groups or materials; common collections are children's literature, young adult literature, and genealogy materials.
