Majors matched to public, academic, school, and archival careers, plus accelerated routes
Almost any bachelor's degree from a regionally accredited college will get you into an ALA-accredited MLIS program, and the University of Washington is typical in naming no required field. Yet the major still shapes which libraries want you afterward. A history degree reads differently in an archive than a computer science degree does in a systems role, and a teaching license matters more for school libraries than any subject.
The question keeps surfacing in librarian communities, including a thread on r/librarians where people ask which degree is most helpful.
The real constraint is not admission but fit: a professional librarian title usually requires the master's, so the bachelor's works best as preparation for a specific library setting and your later MLIS career paths.
The University of Washington asks MLIS applicants for one academic credential: a bachelor's degree from a regionally accredited institution. It specifies no field and no prerequisite courses. That approach is typical. The American Library Association handles MLIS program accreditation but leaves admissions rules to each school, and a 2026 survey of program requirements found the usual baseline is a bachelor's "in any field." Policies are not identical everywhere, so confirm details on each school's admissions page. Still, the idea that you need a library science or English major to get in is a myth.
Most programs publish a minimum GPA of roughly 2.75 to 3.0 on a 4.0 scale. How that number is calculated varies by school:
The 2026 survey also found that some programs offer conditional or provisional admission to applicants under the floor. A GPA a few tenths short is a hurdle to address, not an automatic rejection.
Prerequisite courses are not a universal requirement. A minority of programs require or recommend coursework or skills in research methods, statistics, or basic technology. These policies differ from school to school, so read each program's list carefully.
The GRE has largely disappeared from MLIS admissions. The MLIS programs at Maryland, Missouri, and Washington are no-GRE MLIS programs. The 2026 survey found that none of the programs it sampled required the exam, though some accept optional scores. The notable exception is Indiana University Indianapolis, which asks for GRE scores from applicants who don't meet its GPA minimum (3.0 undergraduate, or 3.2 in a recent graduate degree). Washington also notes that official GRE scores may strengthen a low-GPA petition.
Almost any accredited bachelor's makes you eligible to apply. Being well prepared is a separate question. Your major can shape how competitive your application looks, how quickly you adapt to graduate coursework, and which library settings you're ready to enter. That is where admissions committees start paying closer attention.
Applicants tend to worry that the name on their diploma will decide the outcome, when admissions committees are usually reading something else. Most ALA accredited MLIS programs do not require a particular bachelor's major, so the file is judged as a whole.
Four pieces typically carry the most weight:
A strong statement of purpose connects your coursework to a specific library goal. A biology major might describe wanting to support research data management in a science library. A history major might point to archival research and a plan to work as a special collections librarian. The major becomes evidence for a direction rather than a gap to apologize for.
Choose a major you can earn a high GPA in, then add library experience for MLIS admission. A 3.8 in a subject you enjoy usually serves you better than a 3.0 in a major that merely sounds library-adjacent.
Programs with a defined specialization, such as archives, data science, or health information, may favor a related background. A data-focused track may look for statistics or programming exposure, while a health informatics path may value clinical or biomedical experience. Check each program's admissions page for stated preferences, and if you lack the background, address it through prerequisite coursework or relevant work.
No single major is the best preparation for an MLIS, but some majors clearly fit certain library careers better than others, so start with the kind of library you want to work in and work backward. In the table below, a "strong fit" major is one that builds subject expertise or skills used in that job. It is not an admissions requirement, since most MLIS programs accept applicants from any accredited bachelor's degree.
| Library Path | Strong Undergraduate Majors | Why It Helps | Extra Requirement to Know |
|---|---|---|---|
| Academic library (subject liaison) | History, English, biology, chemistry, economics, or any major matching a university department | Subject knowledge supports research help, library instruction, and collection building for faculty and students in that field | Some research universities prefer or require a second subject master's for certain liaison roles |
| Public library | English, communications, education, psychology, social work, Spanish or other languages | Supports reader's advisory, community programming, outreach, and serving multilingual patrons | Some states have public librarian certification rules for certain positions, and requirements vary by state |
| School library | Education, English, child development | Builds teaching, curriculum, and classroom management skills used daily in K-12 settings | Most states require a teaching license or school library media endorsement, and some also expect classroom teaching experience |
| Archives and special collections | History, art history, classics, foreign languages | Develops primary-source research skills, historical context, and the ability to read older or non-English materials | Optional certification is available through the Academy of Certified Archivists, and many MLIS programs offer archives concentrations |
| Law library | Political science, philosophy, pre-law, history | Builds familiarity with legal concepts, argument, and research methods | Many law library roles, especially academic law library leadership, prefer or require a JD alongside the MLIS |
| Health sciences or medical library | Biology, nursing, public health, chemistry | Helps with medical terminology and literature searching for clinicians, researchers, and students | An optional professional credential (AHIP) is offered through the Medical Library Association |
| Data, digital, or systems librarianship | Computer science, information science, data science, statistics | Supports work with metadata, digital repositories, library systems, and research data services | Employers often look for demonstrated technical skills, such as programming, databases, or a project portfolio |
| Technical services and cataloging | Linguistics, foreign languages, information science | Supports classification, metadata work, and describing materials in multiple languages | Cataloging standards themselves are usually learned in the MLIS, not before it |
Postings tend to ask for a graduate credential first and a subject background second, and the undergraduate major is rarely the headline requirement. No source I could find measures how often postings name a required bachelor's major across all library types, so treat what follows as a pattern, not a percentage.
An overview of ALA JobLIST postings from 2025 to 2026, a window on current Library Hiring Trends, put academic libraries at 66% of listings, public at 20%, special (corporate, government, and similar) at 12%, and school at 2%.1 That mix matters because academic and special roles are where subject expertise is most likely to appear.
A 2025 analysis of 418 US library and information science postings found 299 explicitly required an MLIS, while 119 did not list it, roughly matching the library jobs without an MLIS category.2 A study of 182 academic-library ads from 2022 to 2023 found an ALA-accredited master's required in 85% of them3, a requirement often weighed in the MLIS Degree Debate. Neither study reports bachelor's-major requirements.
The clearest number I located is old: in ads from 2004 to 2009, 5.68% required only a specialized bachelor's degree. It is narrow and dated, so don't read it as a 2026 benchmark.
The practical takeaway: plan on the MLIS, and let your major serve as a bonus for academic or special library work.
A school librarian is a state-credentialed position, which makes this the one library path where your undergraduate degree and a license can matter as much as the MLIS. The American Association of School Librarians (AASL) notes that many states require candidates to hold teacher certification in another subject before they can become school librarians.1 Some states also ask for a master's degree, while others require only certification or licensure.
Texas shows how the pieces stack up. According to the Texas Education Agency, the standard school librarian certificate requires:2
The agency's listed requirements do not spell out a separate classroom teaching license. Its out-of-state process, though, separates classroom teaching certificates from student-services certificates, so check how your own credentials would be classified.3
I could not confirm Oklahoma's current requirements, including whether a separate teaching license or classroom experience is needed, so treat any secondhand summary with caution. The same goes for every other state. Rules change, and no single reliable source offers a complete, current state-by-state comparison.
Before you commit to an undergraduate major, look up school librarian certification requirements by state through your state education agency, and use AASL's licensure overview as a starting point. If school libraries are your goal, an education degree or a subject-teaching major (English, history, science) is the safest choice. It puts you on the licensure track many states expect, and it leaves time to gain the classroom experience some of them require. A different major can still lead to the school librarian MLIS, but it may mean extra certification steps later.
Is an information science or computer science undergraduate degree a better foundation than a humanities major if you want systems, digital libraries, or data services roles? In short: yes for technical library paths, as the MLIS vs. Computer Science comparison explains, but it is not required for MLIS admission.
For systems, digital scholarship, data curation, institutional repositories, and user experience roles, an information science, computer science, or data-focused bachelor's degree is a real advantage. Hiring committees look for comfort with metadata, databases, and library technology stacks. A humanities major offers research, writing, and subject expertise, while a technical major offers the ability to structure data, model systems, and troubleshoot discovery layers. MLIS admissions committees do not require a technical major, so this path is elective rather than gatekeeping.
Academic and special libraries often prefer subject expertise. Science librarian postings may list a STEM background as desired or required, with some 2026 listings favoring undergraduate science or graduate-level sciences library study.12 Health sciences roles typically begin with an ALA-accredited MLIS,3 and biomedical coursework can strengthen candidacy. Law librarian positions often prefer a JD. Special library employers may favor dual credentials such as a law degree, a medical-informatics certificate, or a data-science portfolio, and commonly ask for three to five years of domain experience. For data services and research data positions, postings may also accept an MLIS plus a data science terminal degree or an advanced degree in a relevant discipline alongside library experience.3
A second master's degree is not uniformly required, but Dual MLIS Degrees can strengthen subject-specialist applications. Some academic faculty-rank roles require a second graduate degree,2 and special collections or primary-source positions often value fields like history, area studies, classics, or art history.
These skills are portable across public, academic, and special library settings and can be demonstrated through coursework, internships, or a GitHub portfolio.
Accelerated bachelor's-to-MLIS pathways let you start graduate coursework as an undergraduate and count some credits toward both degrees. They make the most sense if you are already certain you want a library or information career and are enrolled in a qualifying information science major; if you are still exploring careers, the traditional route of finishing any bachelor's first keeps your options open. Figures not stated on official program pages are marked "check program site" so you can confirm current details directly with each school.
| Program | Length | Credit Overlap | Minimum GPA | Approx. Cost | Best For |
|---|---|---|---|---|---|
| University of Maryland BS in Information Science + MLIS (The Universities at Shady Grove) | 3 years total: 2 years undergraduate plus 1 year graduate | Graduate-level courses count toward both degrees; total shared credits not stated (check program site) | Check program site | Graduate tuition and fees per graduate credit, plus a $50-per-credit College of Information fee; undergraduate tuition and fees also apply per graduate credit | UMD Information Science students at Shady Grove with 45 or fewer credits who want both degrees in three years |
| University of Wisconsin-Milwaukee Information Science and Technology BS / MLIS (shared-credit pathway) | Check program site | 21 shared credits: 6 forward-shared and 15 backward-shared | 3.0 in the major to be admitted; must maintain at least a 3.25 overall GPA and at least a 3.5 major GPA | Check program site | UWM Information Science and Technology undergraduates who want to begin graduate work in their fourth year and apply credits to both degrees |
| University of Wisconsin-Milwaukee accelerated IST/MLIS | MLIS shortened to 30 credits; total calendar duration not stated (check program site) | 6 graduate credits taken as part of the bachelor's degree requirements | 2.75 cumulative GPA or higher | Undergraduate tuition applies to the first 6 graduate credits; remaining graduate cost: check program site | Qualified IST students who want to reduce the MLIS to 30 credits and start graduate coursework as seniors |
| University of Oklahoma MLIS (traditional route example) | No accelerated or 4+1 length stated (check program site) | None stated; the bachelor's degree is completed before the MLIS begins | 3.0 cumulative GPA over undergraduate and/or graduate work | Check program site | Applicants from any undergraduate field who finish a bachelor's degree before starting graduate study |
Shorter routes into library school are appealing, but whether they save money depends on how much an MLIS degree costs and how each program is built.
A standard 36-credit MLIS after a bachelor's typically runs about $12,000 to $25,000 at an in-state public school, $20,000 to $40,000 out of state, and $30,000 to $60,000 or more at private schools. A planning range of $25,000 to $45,000 is a reasonable estimate, not a published national median.
Accelerated totals have no reliable national figure. The math is bachelor's tuition plus MLIS tuition, minus any credits the program lets count toward both degrees. Finishing sooner is the clearer benefit. Tuition savings are real only when graduate credits replace required undergraduate ones or a reduced combined rate applies. Check each program's published rules.
Choose the standard route if you want a different major first, such as a subject specialty that academic or special libraries value. It also wins when a low-cost in-state MLIS is available. Published totals range from about $6,400 at UNC Greensboro and $8,843 at Emporia State to $75,096 for Syracuse's online MLIS program in 2026-27. Price differences like that can outweigh the time an accelerated track saves.
MLIS programs admit students from nearly every major, so preparation matters more than the degree title. Use this sequence to build a stronger application during your undergraduate years.
A few months of paid or volunteer library work can do more for your MLIS application than a perfectly matched major. Admissions committees read it as proof that you understand the daily reality of the field.
Pick up library science skills that transfer directly into graduate study. Look for classes or free workshops in metadata, basic cataloging, and database searching. Get comfortable with a library catalog, a spreadsheet, and a content management system. Even a short project, such as tagging a small digital collection, gives you something concrete to describe.
Treat every role as a source of two things: a story and a reference.
For your statement of purpose, choose one specific moment per experience. Maybe you fixed a confusing shelving system, helped a patron find a hard-to-locate source, or cleaned up inconsistent records. Describe the problem, what you did, and what it taught you about the profession.
For recommendations, supervisors who watched you work are stronger choices than people who only know your grades. Ask early, share your goals, and give them a short summary of your accomplishments.
For more on getting started, see our guides to MLIS Entry-Level Jobs and to applying for an MLIS with no prior experience.
The worry most career-changers carry into an MLIS application is that a degree in business, teaching, nursing, or the arts somehow counts against them. It doesn't. Admissions committees read a non-library background as a bundle of transferable skills for library science, and your job is to translate it for them.
Every prior field maps onto library work. Spell out the connection rather than assuming it is obvious.
Four short moves keep your essay focused:
1. Past work: what you did and what you got good at. 2. The gap: the moment you realized you wanted to work with information, access, or communities instead. 3. The library goal: the specific role or setting you are aiming for. 4. Why this program: name features of the school that match that goal.
Three-year degrees, international credentials, and older transcripts raise equivalency questions, not rejection. Many programs accept a bachelor's from any accredited field, but mlis admissions requirements vary. Before you apply, email each program's admissions office directly and confirm how your degree is evaluated. Ask whether a credential evaluation (such as WES) is needed and whether your GPA will be recalculated. Getting this answer in writing early saves you from a surprise late in the cycle.
Can you be a librarian with just a bachelor's degree? Generally not for professional librarian titles, which most employers tie to a master's in library and information science, though library assistant, library technician, and some school or small-library roles are open to bachelor's holders. The figures below are national 2025 wage and employment estimates from the U.S. Bureau of Labor Statistics. They describe what each occupation pays across all workers, not what graduates of any one degree earn, so treat them as approximate and keep in mind that the MLIS is the credential that unlocks the higher-paid professional and teaching roles shown here.
| Occupation (BLS, 2025) | U.S. Employment | Mean Annual Wage | 25th Percentile | Median Annual Wage | 75th Percentile |
|---|---|---|---|---|---|
| Librarians, Curators, and Archivists (broad group, includes curators, archivists, and related support roles) | 234,910 | $63,900 | $45,480 | $60,470 | $78,000 |
| Librarians and Media Collections Specialists | 133,790 | $72,840 | $56,310 | $68,270 | $84,480 |
| Education and Library Science Teachers, Postsecondary | 64,460 | $79,840 | $55,740 | $75,640 | $97,840 |
| Library Science Teachers, Postsecondary | 3,630 | $88,110 | $64,080 | $80,340 | $100,910 |
