The traditional concept of a library is being redefined from a place to access paper records or books to one that also houses the most advanced electronic resources, including the Internet, digital libraries, and remote access to a wide range of information sources. Consequently, librarians, often called information professionals, combine traditional duties with tasks involving quickly changing technology. Librarians help people find information and use it effectively for personal and professional purposes. They must have knowledge of a wide variety of scholarly and public information sources and must follow trends related to publishing, computers, and the media to oversee the selection and organization of library materials. Librarians manage staff and develop and direct information programs and systems for the public and ensure that information is organized in a manner that meets users' needs.
Librarian positions focus on one of three aspects of library work: user services, technical services, and administrative services. Librarians in user services, such as reference and children's librarians, work with patrons to help them find the information they need. The job involves analyzing users' needs to determine what information is appropriate and searching for, acquiring, and providing the information. The job also includes an instructional role, such as showing users how to find and evaluate information. For example, librarians commonly help users navigate the Internet so they can search for and evaluate information efficiently. Librarians in technical services, such as acquisitions and cataloguing, acquire, prepare, and classify materials so patrons can find it easily. Some write abstracts and summaries. Often, these librarians do not deal directly with the public. Librarians in administrative services oversee the management and planning of libraries: they negotiate contracts for services, materials, and equipment; supervise library employees; perform public-relations and fundraising duties; prepare budgets; and direct activities to ensure that everything functions properly.
In small libraries or information centers, librarians usually handle all aspects of library operations. They read book reviews, publishers' announcements, and catalogues to keep up with current literature and other available resources, and they select and purchase materials from publishers, wholesalers, and distributors. Librarians prepare new materials, classifying them by subject matter and describing books and other library materials to make them easy to find. Librarians supervise assistants, who enter classification information and descriptions of materials into electronic catalogs. In large libraries, librarians often specialize in a single area, such as acquisitions, cataloguing, bibliography, reference, special collections, or administration. Therefore, good teamwork is important.
Librarians also recommend materials. Many analyze collections and compile lists of books, periodicals, articles, audiovisual materials, and electronic resources on particular subjects. They collect and organize books, pamphlets, manuscripts, and other materials in a specific field, such as rare books, genealogy, or music. In addition, they coordinate programs such as storytelling for children and literacy skills and book talks for adults. Some conduct classes, publicize services, write grants, and oversee other administrative matters.
Many libraries have access to remote databases and maintain their own computerized databases. The widespread use of electronic resources makes database-searching skills important for librarians. Librarians develop and index databases and help train users to develop searching skills. Some libraries are forming consortiums with other libraries to allow patrons to access a wider range of databases and to submit information requests to several libraries simultaneously. The Internet also has greatly expanded the amount of available reference information. Librarians must know how to use these resources and inform the public about the wealth of information they contain.
Librarians are classified according to the type of library in which they work: a public library; school library media center; college, university, or other academic library; or special library. Librarians in special libraries work in information centers or libraries maintained by government agencies or corporations, law firms, advertising agencies, museums, professional associations, unions, medical centers, hospitals, religious organizations, or research laboratories. They acquire and arrange an organization's information resources, which usually are limited to subjects of special interest to the organization. They can provide vital information services by preparing abstracts and indexes of current periodicals, organizing bibliographies, or analyzing background information and preparing reports on areas of particular interest. For example, a special librarian working for a corporation could provide the sales department with information on competitors or new developments affecting the field. A medical librarian may provide information about new medical treatments, clinical trials, and standard procedures to health professionals, patients, consumers, and corporations. Government document librarians, who work in a variety of depository libraries in each of the States, preserve and disseminate government publications, records, and other documents that make up a historical record of government actions.
Some librarians work with specific groups, such as children, young adults, adults, or the disadvantaged. In school library media centers, librarians—often called school media specialists—help teachers develop curricula and acquire materials for classroom instruction. They also conduct classes for students on how to use library resources for research projects.
Librarians with computer and information systems skills can work as automated-systems librarians, planning and operating computer systems, and as information architects, designing information storage and retrieval systems and developing procedures for collecting, organizing, interpreting, and classifying information. These librarians analyze and plan for future information needs. Automated information systems enable librarians to focus on administrative and budgeting responsibilities, grant writing, and specialized research requests, while delegating more routine services responsibilities to technicians.
More and more, librarians apply their information management and research skills to arenas outside of libraries—for example, database development, reference tool development, information systems, publishing, Internet coordination, marketing, Web content management and design, and training of database users. Entrepreneurial librarians sometimes start their own consulting practices, acting as freelance librarians or information brokers and providing services to other libraries, businesses, or government agencies.
Librarians and library media specialists held about 143,500 jobs in 2020. The largest employers of librarians and library media specialists were as follows:
- Elementary and secondary schools; state, local, and private - 33%
- Local government, excluding education and hospitals - 29%
- Colleges, universities, and professional schools; state, local, and private - 17%
- Information - 8%
Most librarians and library media specialists typically work on the floor with patrons, behind the circulation desk, or in offices. Some have private offices, but those in small libraries usually share work space with others.
Most librarians and library media specialists work full time, although part-time work is common. Public and academic librarians often work on weekends and evenings and may work holidays. School librarians and library media specialists usually have the same work and vacation schedules as teachers, including summers off. Special librarians, such as corporate librarians, typically work normal business hours but may need to work more than 40 hours per week to help meet deadlines.
Education & Training Required
Entry into a library science graduate program requires a bachelor's degree, but any undergraduate major is acceptable. Many colleges and universities offer library science programs, but employers often prefer graduates of the 49 schools in the United States accredited by the American Library Association. Most programs take 1 year to complete; some take 2. A typical graduate program includes courses in the foundations of library and information science, such as the history of books and printing, intellectual freedom and censorship, and the role of libraries and information in society. Other basic courses cover the selection and processing of materials, the organization of information, research methods and strategies, and user services. Prospective librarians also study online reference systems, Internet search methods, and automated circulation systems. Elective course options include resources for children or young adults; classification, cataloguing, indexing, and abstracting; and library administration. Computer-related course work is an increasingly important part of an MLS degree. Some programs offer interdisciplinary degrees combining technical courses in information science with traditional training in library science.
The MLS degree provides general preparation for library work, but some individuals specialize in a particular area, such as reference, technical services, or children's services. A Ph.D. in library and information science is advantageous for a college teaching position or a top administrative job in a college or university library or large public library system.
States generally have certification requirements for librarians in public schools and local libraries, though there are wide variations among States. School librarians in 20 States need a master's degree, either an MLS or a master's in education with a specialization in library media. In addition, over half of all States require that school librarians hold teacher certifications, although not all require teaching experience. Some States may also require librarians to pass a comprehensive assessment. Most States also have developed certification standards for local public libraries, although in some States these guidelines are voluntary.
Other Skills Required
In addition to an MLS degree, librarians in a special library, such as a law or corporate library, usually supplement their education with knowledge of the field in which they are specializing, sometimes earning a master's, doctoral, or professional degree in the subject. Areas of specialization include medicine, law, business, engineering, and the natural and social sciences. For example, a librarian working for a law firm may hold both library science and law degrees, while medical librarians should have a strong background in the sciences. In some jobs, knowledge of a foreign language is needed.
Librarians participate in continuing education and training to stay up to date with new information systems and technology.
How to Advance
Experienced librarians can advance to administrative positions, such as department head, library director, or chief information officer.
Employment of librarians and library media specialists is projected to grow 9 percent from 2020 to 2030, about as fast as the average for all occupations.
About 15,200 openings for librarians and library media specialists are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
Communities are increasingly turning to libraries for a variety of services and activities. Therefore, there will be a need for librarians to manage libraries and help patrons find information. Parents value the learning opportunities that libraries present for children because libraries have information and learning materials that children often cannot access from home. In addition, the availability of electronic information and media materials is expected to increase the demand for these workers in research and special libraries, where patrons may need help sorting through the large amount of digital information and collections materials.
The median annual wage for librarians and library media specialists was $61,190 in May 2021. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less.
