A library technician or library assistant is a skilled library and information paraprofessional trained to perform the day-to-day functions of a library, and assists librarians in the acquisition, preparation, and organization of information. They also assist library patrons in finding information. 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) that were once performed exclusively by librarians. Especially in small village libraries, a library technician may be the only person (or one of only a few) staffing the library. In larger libraries, they may help run certain departments and supervise library clerks, aides, and volunteers. Because libraries are increasingly using new technologies (such as automated databases, CD-ROM, the Internet, and virtual libraries), the role of the library technician is expanding and evolving accordingly. Qualifications Library technicians differ from librarians in terms of education and main duties. Library technicians typically require a diploma, or, ideally, an associate degree in library technology from a community college or other similar institution, whereas librarians require a master's degree in library science from an accredited university-based graduate school of library and information science. 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. However, for varying reasons, not all librarians are trained yet at the graduate level as professional societies and legal statutes would prefer, and so, as indicated above, sometimes technicians or other individuals with enough training must fill the role. Tasks Library technicians will often carry out the practical tasks involved in daily library operation, whereas librarians generally perform the managerial, supervisory and administrative functions. For example, a librarian may be responsible for creating a library's collection development policies, which would include selection criteria for purchasing of items. A library technician would then purchase items based on these criteria. Library technicians may also be graduates of a four-year college, or institute. They could also be holders of a certificate, associate degree, or bachelor's degree. Because the education of the library technician is practical, broad, and skills-based, they are job-ready upon graduation; the only training they may require is that which is specific to their particular place of employment. Duties can vary with the type and size of the library but can include: cataloguing and classification of materials, data
