A Master's in Library and Information Science (MLIS) is a graduate degree that prepares professionals to organize, manage, and provide access to information across a wide range of settings. You may also see it called a Master of Library Science (MLS). The two names are functionally the same credential, and employers treat them interchangeably.
MLIS programs typically cover a blend of theory and applied practice, including:
The MLIS is the terminal professional degree for most librarian positions in public, academic, school, and special library settings. Many job postings specifically require an MLIS from an ALA-accredited program as a baseline qualification.
The degree also opens doors to roles outside traditional library environments. Graduates increasingly move into UX research, data governance, taxonomy design, content strategy, and knowledge management, applying information science principles in corporate, nonprofit, and government organizations. Understanding the full range of skills you learn in a Master's in Library Science program can help you see just how versatile this credential has become.
The American Library Association (ALA) Committee on Accreditation evaluates master's programs in library and information science against rigorous standards covering curriculum, faculty qualifications, student support, institutional resources, and more.1 As of 2024, 67 programs across 63 institutions hold ala accredited programs.2 The committee adopted updated 2023 Standards for Accreditation in late 2023, integrating equity, diversity, and inclusion principles throughout its core review areas.3
Most public and academic library systems require or strongly prefer candidates who hold degrees from ALA-accredited programs. In many states, professional librarian certification mandates an ALA-accredited master's degree. Graduating from a non-accredited program can significantly narrow your library science careers, even if the coursework is comparable.
A common concern among prospective students is whether an online MLIS is viewed differently by employers. The answer is straightforward: ALA accredits the program itself, not the delivery format. A fully online mlis degree from an ALA-accredited institution carries the same credential as its on-campus counterpart. Schools like Syracuse University and the University of Denver, for example, hold full ALA accreditation for their online MLIS offerings.2 Always verify a program's current accreditation status directly through the ALA before enrolling.
Across the top-ranked online MLIS programs, approximate net prices range from roughly $12,000 to $36,000, while median institutional debt clusters between $19,000 and $22,500. The University at Buffalo stands out with an ROI ratio of approximately 3.73, meaning graduates earn roughly $3.73 for every dollar of debt over 10 years, followed closely by the University of Wisconsin-Madison at 3.60. Even the lowest-ROI program in the top seven, the University of Southern Mississippi, still returns nearly $1.96 per debt dollar.
Online MLIS programs offer a wide range of concentration areas that directly shape your career trajectory. Among the top ranked programs, common specializations include:
Choosing a specialization early helps you build a focused portfolio and align fieldwork or capstone projects with your target role. You can explore paths such as Master's in Library Science in Archival Science Degree Online, Master's in Library Science in School Librarianship Degree Online, or Master's in Library Science in Digital Libraries Degree Online to compare curricula in depth.
Admissions requirements across these programs are broadly consistent. You will typically need a bachelor's degree in any field, official transcripts, a statement of purpose, a resume, and one to three letters of recommendation. Most programs require a minimum 3.0 GPA, though some, like Louisiana State University, offer probationary admission with a GPA as low as 2.75.
A significant trend favoring applicants: the majority of top online MLIS programs are now test-optional or GRE-free. Texas Woman's University, the University of Arizona, the University at Buffalo, the University of Southern Mississippi, the University of Denver, and Louisiana State University all waive the GRE. The University of Wisconsin-Madison may still require it, so check current policies before applying. For a full list, see our guide to no-GRE MLIS options.
Credit requirements typically range from 36 to 42 hours, with the University of Southern Mississippi requiring 40 credits and the University of Arizona requiring 37. Full-time students generally finish in about two years, while part-time students should plan for three to four years. The University of Denver advertises an accelerated 21-month timeline, and the University of Southern Mississippi offers completion in as few as one year.
Most programs deliver coursework asynchronously, giving working professionals maximum scheduling flexibility. However, the University of Southern Mississippi uses synchronous online sessions with live weekly meetings, and the University of Wisconsin-Madison offers a hybrid format. Understanding these delivery differences is important when balancing your MLIS with professional or personal commitments.
A master's in library and information science opens doors well beyond traditional library roles. Understanding what graduates actually earn and where the jobs are can help you evaluate your return on investment before committing to a program.
According to the Bureau of Labor Statistics, librarians and library media specialists earned a median annual wage of $64,320 in 2024.1 The pay range is wide: entry-level positions at the 10th percentile start around $38,920, while experienced professionals at the 90th percentile earn upward of $100,880.2 Factors such as geographic location, employer type, and specialization heavily influence where you land on that spectrum. For a detailed breakdown by work setting, see our Master's in Library Science Career Pay & Salary guide.
Program-level earnings data from the College Scorecard was not available for the MLIS programs in our ranking at the time of publication. That gap is common for smaller graduate cohorts, so BLS occupational benchmarks remain the most reliable reference point.
The BLS projects 2% employment growth for librarians and library media specialists from 2023 to 2033, with roughly 2,400 openings expected annually.1 That steady pace reflects ongoing retirements and the expansion of digital services in public, academic, and special library settings. Archivists, curators, and museum workers (SOC 25-4011) represent a related occupational group that also draws heavily from MLIS graduates.
The degree's versatility is a key selling point. Roles in user experience research and information architecture increasingly appear in tech companies, healthcare systems, and government agencies, expanding Library science jobs far beyond library walls.
Choosing the right online master's in library science program raises many practical questions about timelines, costs, and career outcomes. Below are concise answers to the questions prospective MLIS students ask most often.
