The ODLIS defines a school library as "a library in a public or private elementary or secondary school that serves the information needs of its students and the curriculum needs of its teachers and staff, usually managed by a school librarian or media specialist."
Working in a school library involves varied tasks, interaction with students, teachers, staff, parents and community members . . . and lots of flexibility. Secondary school libraries are often staffed by a professional librarian with the support of one or more library assistants full or part-time. The librarian's schedule in a secondary school is often more flexible and varied, depending on classroom projects needing support at various times through the school year. Elementary school librarians may work alone and work a more "fixed" schedule - classrooms come in on a scheduled basis at the same time each week for more formalized library programming.

School districts vary on the educational and experience required to be a school librarian. In Colorado Springs, some school districts require a teaching certificate with a library content area test. Other school districts also require a Master of Library Science degree. Smaller school districts may hire one librarian in the district with a teaching certificate and masters degree. This "professional" librarian will often staff the high school with additional libraries in the district being staffed by "classified" or non-professional librarians. Large school districts may centralize library services such as cataloging and physical material prep so they are delivered to each school shelf ready.
