Librarian Job Description

A librarian builds, organizes and explains collections of information so that people can find what they need and judge whether it holds up. BLS files the work under Librarians and Media Collections Specialists (SOC 25-4022), and its Occupational Outlook Handbook lists the core tasks plainly: create and use databases of library materials, organize materials so they are easy to find, and help patrons conduct research and evaluate search results. The setting changes nearly everything else about the day.

In a public library, the librarian is a generalist serving whoever walks through the door. A morning might open with a toddler storytime, shift to a reference desk stint where questions run from genealogy to filing an online unemployment claim, and close with an order list for the adult nonfiction budget line. Public librarians also plan programs: tax help nights, English conversation groups, and drop-in tech help for patrons setting up a phone or an email account.

On a college or university campus, the job tilts toward teaching and research support. A liaison librarian assigned to the biology or history department builds research guides in a platform such as Springshare's LibGuides, teaches one-shot instruction sessions on database searching, and answers faculty questions about citation managers, open access options and data management plans for grant proposals. Academic librarians also select and license e-resources, which means reading vendor contracts for simultaneous user limits, interlibrary loan rights and text and data mining terms.

In a K-12 school, the librarian (sometimes titled school library media specialist) works beside classroom teachers: co-planning research units, showing students how to tell a vetted source from a content farm, running reading promotions, and managing the school catalog and its device and makerspace collections.

Behind the public desk, the technical base is shared across settings. Librarians catalog new titles as MARC 21 records following RDA (Resource Description and Access), assign Library of Congress or Dewey call numbers, and work inside an integrated library system such as Ex Libris Alma, FOLIO, Koha, Polaris or Follett Destiny. They pull usage reports to decide which subscriptions to renew and which worn or outdated print to weed. In larger systems they supervise library technicians, assistants and student workers, build desk schedules and train new hires on circulation policy.

The job carries a civic side as well. Librarians draft and apply collection development policies, process requests to reconsider materials, guard patron privacy in circulation records, and explain those policies to library boards, principals or deans when a decision draws attention.

A strong librarian is as comfortable building a cost-per-use spreadsheet for a database renewal as talking a nervous first-year student through a keyword search. Both are information work. The second one simply happens in public, with someone waiting for an answer.

Education. BLS says librarians typically need a master's degree in library science (MLS) and that these programs typically take 1 to 2 years to complete, with coursework covering research methods and strategies, online reference systems and internet search techniques. As a rough guide, the safest choice for a public or academic library career is a master's from a program accredited by the American Library Association. Degree names differ (MLS, MLIS, MSLIS, MI); what to check is the program's accreditation status.

School library jobs follow their own path. BLS notes that public school librarians and library media specialists typically need a teacher's certification, and that requirements vary by state. Look up the state education agency's licensure page early, because the endorsement route, required coursework and any exam are set at the state level.

Specialist credentials. Health sciences librarians can apply to the Academy of Health Information Professionals (AHIP), the Medical Library Association's peer-reviewed, portfolio-based certification and career development program. Librarians who handle born-digital collections and archives can earn the Digital Archives Specialist (DAS) certificate from the Society of American Archivists.

Experience. The master's degree is the entry ticket. Practicum hours, a graduate assistantship in a campus library, or paraprofessional work as a library technician or circulation assistant gives a new graduate concrete examples to bring to an interview. As a rough guide, plan on 3 to 5 years of professional work, including some supervision, before applying for a branch manager or department head post.

Technical skills worth building:

• Cataloging and metadata: MARC 21, RDA, Library of Congress Subject Headings, and some exposure to BIBFRAME linked data
• Integrated library systems: Alma, FOLIO, Sierra, Koha, Polaris, Destiny
• Databases and discovery: EBSCOhost, ProQuest, JSTOR, PubMed, and Westlaw or Lexis for legal research
• Resource sharing: OCLC WorldShare and ILLiad for interlibrary loan
• E-resource management: COUNTER usage reports, license review, link resolver and proxy troubleshooting
• Instruction: lesson planning, short assessments, and research guide authoring

Working habits that matter: patience with vague or half-formed questions, care with metadata (a bad record can hide a book from search), plain-language teaching for every age group, and steady judgment under public pressure, whether the pressure comes from a patron complaint or a formal challenge to a title on the shelf. Comfort with budgets and vendor negotiation rounds out the profile for anyone headed toward collection management.

BLS projects employment of librarians and library media specialists to grow 3 percent from 2025 to 2035, a pace it describes as about as fast as the average for all occupations. That is an employment change of 3,600 jobs on a base of 142,300 jobs in 2025. The more useful figure for a job seeker is turnover: BLS projects about 12,600 openings a year on average over the decade, and says many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force.

Where the jobs sit shapes an education-sector career. In the OOH list of largest employers, local government outside education and hospitals (which includes public library systems) held 32 percent of jobs, local elementary and secondary schools 31 percent, state colleges and universities 9 percent, and private colleges and universities 8 percent. Pay varies by sector as well. In May 2025 OEWS data, the median for the occupation in educational services was $74,120, with a 10th percentile of $48,190 and a 90th percentile of $108,770. In local government, excluding schools and hospitals, the median was $62,860.

Academic library collections are now largely digital. ACRL's report The State of U.S. Academic Libraries, based on its annual survey for fiscal year 2024, found that 79.6 percent of academic library collections are in digital or electronic format and that digital materials account for 93.2 percent of total circulation. Librarians made up about a third (35 percent) of total staff FTE, alongside other professional staff, student assistants and other paid staff. For a candidate, those figures describe a job built around licensed digital content: renewals, access troubleshooting, discovery settings and teaching people to search well.

The same report flags a data gap. ACRL weighted its 2024 results to stay representative of U.S. academic libraries beyond the sunset of the federal IPEDS Academic Libraries component after FY 2024, and it says it is working to keep providing data for peer comparisons. A total of 1,367 U.S. institutions completed that survey, a 39.5 percent response rate. Assessment, such as compiling usage evidence for a dean, remains part of academic library work.

The other shift is artificial intelligence. In October 2025 the ACRL Board of Directors approved AI Competencies for Academic Library Workers, written by a task force created in July 2024. The framework is organized under four headings: Ethical Considerations, Knowledge & Understanding, Analysis & Evaluation, and Use & Application. ACRL states that it is not possible to create a set of competencies that apply uniformly to everyone, so the document serves as a base for training programs and for local frameworks rather than a checklist. In practice, a librarian who can explain how a chatbot produced a citation, check whether that citation exists, and teach students to run the same check is doing core reference work.

For new graduates, the openings are real but spread across settings with different hiring calendars: school districts on an academic-year calendar, campuses through search committees, and public systems under their own city or county hiring rules. Applying across more than one setting widens the field.

Dear Search Committee,

I am applying for the Librarian position at Lakeshore Community College, where the posting describes a role split between reference, instruction and e-resource management. That split describes the last three years of my working life, and I would like to bring it to your campus.

I finished my MLIS at an ALA-accredited program two years ago while working as a library technician at a regional public library. The technician job taught me the back end: I cleaned up several thousand MARC records after a migration to a new integrated library system, built the holds workflow our circulation desk still uses, and trained four part-time staff on it. It also taught me patience at the desk, where a question about a tax form can turn into an hour of help with an online benefits application.

Since graduating I have worked as an instruction librarian on contract at a state university. I teach one-shot sessions for first-year composition and nursing, maintain eleven research guides, and co-designed a short workshop on checking citations produced by generative AI tools. Students bring me chatbot reference lists; we test each entry against the catalog and the databases, and they leave knowing how to do it alone. Faculty in the nursing program asked me to fold the workshop into their research methods course this fall.

Your college serves many working adults and dual-enrollment high school students. I would welcome the chance to build evening and online instruction for both groups, and to review your database renewals with cost-per-use data before the next budget cycle.

Thank you for your time. I would be glad to talk through a sample lesson plan or a collection assessment with the committee.

Sincerely, Jordan Alvarez
