How to become a librarian:
the MLIS, the job market, and what it actually involves.Librarianship is a graduate-level profession — the Master of Library and Information Science (MLIS) is the standard entry credential for professional librarian positions. The work itself has evolved dramatically: modern librarians manage digital collections, teach information literacy, provide reference services, run community programs, and increasingly work in specialized settings like law firms, hospitals, and corporations. This guide covers what the path actually looks like.

The step-by-step path
What the real process looks like, in order.
Understand the different types of librarian roles
Librarian is a broad title covering very different work environments. Public librarians work in public library systems serving community members of all ages. Academic librarians work in college and university libraries. School librarians (library media specialists) work in K-12 schools and often need a teaching credential in addition to an MLIS. Special librarians work in law firms (law librarians), hospitals (medical librarians), corporations, and government agencies. Each setting has different hiring requirements, salary ranges, and day-to-day work.
- Research the four main library settings: public, academic, school, and special — salary and job availability vary significantly by setting
- Visit or volunteer at different library types to experience the actual work before committing to a specialization
- Understand that school librarians in most states need both an MLIS and a state teaching license or library media specialist certification
- Note that special librarians (corporate, law, medical) often earn significantly more than public or school librarians
Earn your MLIS from an ALA-accredited program
The Master of Library and Information Science (MLIS) — also called MLS, MSLIS, or similar depending on the school — from an ALA-accredited program is the required credential for professional librarian positions in virtually all settings. There are 60+ ALA-accredited programs in the US and Canada. Many are available fully online, making the degree accessible without relocating. The quality of ALA-accredited programs is relatively consistent; choose based on specialization offerings, cost, and whether you can attend online.
- Verify any program you're considering is ALA-accredited — non-accredited library degrees are not recognized for professional librarian positions
- Choose your specialization: archives, digital libraries, children's services, academic libraries, health sciences, law librarianship, data curation, etc.
- Consider the cost carefully — MLIS programs range from $15,000 (in-state public universities) to $50,000+ (private institutions); online programs from state universities often offer the best value
- Begin gaining library work experience during your MLIS — most programs have practicum or internship requirements, and paraprofessional library jobs are widely available
- Apply for graduate assistantships at university libraries — these provide tuition remission and a salary while giving you direct library experience
Build experience through paraprofessional work and internships
Library paraprofessional positions (library assistant, library technician, circulation specialist) are available with a bachelor's degree and provide valuable experience and income while you complete your MLIS. Many librarians work in paraprofessional roles for 1–5 years before entering MLIS programs. This experience makes you a significantly stronger candidate upon graduation.
- Apply for library assistant or library technician positions at public, academic, or special libraries in your area
- Complete your MLIS practicum or fieldwork in a library setting aligned with your target specialty
- Volunteer for additional library projects beyond your required hours — event programming, collection development, digital projects
- Join the American Library Association (ALA) as a student member — the networking, journals, and job boards are directly valuable
Obtain any required state certification (especially for school librarianship)
Public librarians don't typically require state certification beyond the MLIS, though some states have additional requirements. School librarians almost always need a state school library media specialist license or endorsement in addition to the MLIS. Requirements vary by state and often include a teaching credential component. Academic and special librarians rarely need state certification.
- Research your target state's requirements for the type of librarianship you're pursuing
- If targeting school librarianship, identify whether your state requires a teaching license and build that into your education timeline
- Apply for state public librarian certification if your state requires it — most states with requirements process applications online
- Check reciprocity agreements if you plan to work across state lines — some states recognize other states' certifications
Navigate the job market strategically
The library job market is more competitive than the MLIS program enrollment numbers suggest — more people graduate each year than there are open positions in many settings, particularly public and academic libraries. School libraries and special libraries (especially law and medical) tend to have better supply-demand ratios. Geographic flexibility significantly expands your opportunities.
- Search library-specific job boards: ALA JobLIST, LISjobs.com, LibGig, Indeed with library filters, and your state library association's job board
- Be geographically flexible if possible — entry-level librarian positions in rural areas and smaller markets are less competitive than major metros
- Pursue specializations with strong demand: health sciences librarianship, law librarianship, digital services, and data management are in higher demand than general reference
- Consider temporary or part-time positions as entry points — many librarians start as substitute or on-call librarians while waiting for a full-time position
- Network through ALA divisions, state library associations, and alumni networks — many library positions are filled through professional community connections

What most guides won't tell you
The honest realities of this career path.
The job market is more competitive than it looks on paper. Hundreds of MLIS graduates compete for each desirable public or academic library opening. People who get hired are typically those with specializations, relevant experience, and geographic flexibility.
Salaries in public libraries are modest, especially at entry level. Starting public librarian salaries of $40,000–$52,000 are common outside major metros, and many public library systems have salary caps that limit long-term earning growth. Special libraries pay significantly better.
The profession is evolving fast. Librarianship in 2025 involves significant technology work: managing digital collections, teaching data literacy, implementing discovery systems, and navigating AI tools for information management. Candidates who approach the profession as 'working with books' will be at a disadvantage.
School library positions are frequently cut in budget crises. School librarians face ongoing job insecurity in many districts where administrators view the position as discretionary. This is a real risk worth factoring into career planning.
Is this career right for you?
Great fit if…
- You genuinely value information access, literacy, and connecting people with resources — intrinsic motivation matters enormously in a field with salary constraints
- You're intellectually curious across many subjects and enjoy helping people find and evaluate information effectively
- You're comfortable with technology and interested in how digital systems organize and deliver information
- You value community service and see the library as a public institution worth sustaining
May not be right if…
- You're primarily motivated by income — librarianship is a meaningful but modestly compensated profession in most public settings
- You imagine librarianship as quiet book-cataloging work — modern librarians manage programs, teach classes, navigate technology systems, and serve diverse community needs
- You're unwilling to be geographically flexible — the best positions are rarely where you currently live, especially at entry level
