Experienced library technicians can advance by obtaining a Master of Library Science degree. Library technicians are assuming greater responsibilities, in some cases taking on tasks previously performed by librarians. Depending on the employer, library technicians can have other titles, such as library technical assistants. Library technicians direct library users to standard references, organize and maintain periodicals, prepare volumes for binding, handle interlibrary loan requests, prepare invoices, perform routine cataloguing and coding of library materials, retrieve information from computer databases, and supervise support staff. The widespread use of computerized information storage and retrieval systems has resulted in technicians handling more technical and user services, such as entering catalogue information into the library's computer, that were once performed by librarians.
Technicians assist with customizing databases.
In addition, technicians instruct patrons how to use computer systems to access data. The increased use of automation has reduced the amount of clerical work performed by library technicians. Many libraries now offer self-service registration and circulations with computers, decreasing the time library technicians spend manually recording and inputting records. Some library technicians operate and maintain audiovisual equipment, such as projectors, tape recorders, and videocassette recorders, and assist users with microfilm or microfiche readers. They also design posters, bulletin boards, or displays.
