The widespread use of computerized information storage and retrieval systems has resulted in library technicians assisting in the handling of technical services (such as cataloguing).
Typically, a librarian will have had an undergraduate baccalaureate degree in either library science or a field in which they wish to specialize, like history, prior to graduate study.
For example, a librarian may be responsible for creating a library's collection development policies, which would include selection criteria for purchasing of items.
Because the education of the library technician is practical, broad, and skills-based, they are job-ready upon graduation; the only training they require is specific to their particular place of employment.
In smaller libraries, where the foundations of organization and operation are already established, such paraprofessionals sometimes serve as the manager or even the sole staff member.
