Your Guide to Master’s in Library Science Online Programs (MLIS)

Working in a library may require more than a love of information and books. Those interested in working in libraries across the country can pursue a master’s in library science, also known as a master’s degree in library and information studies, or MLIS.

A master’s in library science is a graduate-level degree focusing on the cataloging and study of printed texts and digital media. A typical MLIS program covers general topics, such as the theoretical components of librarianship and more hands-on lessons about database management and organization.

The American Library Association is the accrediting body for degrees in library and information studies. The association accredits all MLIS programs in the United States and Canada. Those who want to pursue a librarian career in the United States and Canada can attend an ALA-accredited degree program.

Due to advanced technology, librarianship in 2025 is very different from what it was even 10 years ago. Some would-be librarians are turning to online master’s in library science programs to develop technology skills while gaining the knowledge they need to work in libraries. An online MLIS helps ensure a greater understanding of library resources, including technology-driven resources.

Online MLIS Curriculum

Courses in online library and information studies vary by school but typically include the evaluation and management of information, cross-disciplinary learning and hands-on experience. Courses may include:

• Information architecture: The structural organization of data or shared information environments such as the art and science of labeling websites, data sets, intranets or other repositories of information.
• Information science and technology: Courses in this category explore fundamental information science theories and information technologies. Theory and technology can be discussed and applied to practical purposes in library and information services.
• Research methods: These courses cover advanced research methods including how to recognize and define a research problem in a professional setting to improve professional practice; how to select and use appropriate research methods such as sampling design, survey, experiment, qualitative field research and unobtrusive research to gather original data to solve the research problem and increase knowledge about the domain; how to use analytic methods like quantitative statistical analysis and qualitative analysis to analyze and synthesize the collected data into a solution to the identified research problem; and how to prepare a professional research proposal.
• User-centered information services: The study of a library system that is user-centered as opposed to systems-centered. This area of study considers how libraries and other information technology can be organized to best suit the end user.
• Computer science: General coursework in computer science can help MLIS students better understand data science, data analytics and data management; institutional repository management; digital libraries and digital preservation; networking hardware and software skills required to manage a computer network; integrated library systems utilizing relational databases and database design; and informatics.

Every MLIS program is unique in its requirements and course loads. The ALA requires the following standards for accredited master’s programs in library and information studies curricula:

• Foster the development of library and information professionals who will assume leadership roles in providing services and collections appropriate to the communities they serve.
• Emphasize an evolving body of knowledge that reflects the findings of basic and applied research from relevant fields.
• Integrate technology and the theories that underpin its design, application and use.
• Respond to the needs of a diverse and global society, including the needs of underserved groups.
• Provide direction for future development of a rapidly changing field.
• Promotes commitment to continuous professional development and lifelong learning, including the skills and competencies that are needed for the practitioner of the future.

Online MLIS Admissions Requirements

Each online MLIS program will have its own admissions requirements and prerequisites. For detailed information about the application process you should visit a school’s admissions website. However, there are some components that you should prepare to complete:

1. Application: Most programs require some form of application on their admissions website.
2. Bachelor’s degree: To qualify for admission to MLIS programs, you must have a bachelor’s degree in some field. There are relatively few undergraduate library science programs, so don’t worry if that is not your field of study.
3. Transcripts: Request transcripts from your undergraduate institution in advance of graduate program application deadlines.
4. Test scores: Many schools require GRE General Test scores or TOEFL/IELTS scores for international students. Check with the program you are applying to, as not all schools require test scores.
5. Resume/CV: Prepare a resume with relevant education and work history and include this in your application.
6. Personal statement: Be prepared to write a short essay about who you are and why you are applying for this online MLIS program. Personal statements should be tailored to the specific program and school.
7. Letters of recommendation: Get letters of recommendation from academic mentors, professional contacts or other credible people who can attest to your academic ability. The number of letters required will vary by school.

Online Master’s in Library Science Concentrations

Some library science master’s programs allow you to concentrate in specific areas. While not available at every school, according to the ALA, concentrations can include:

• School librarianship
• Art librarianship
• Health science librarianship
• Database design
• Archival studies

Concentrations allow a student to dive deeper into an aspect of library management.

For example, with a concentration in school media, a librarian is better equipped to deal with the demands of working in an academic setting. Programs in school media offer insight into developing and managing educational media and providing library services and resources to students of all ages. Similarly, a concentration in information management may help students gain skills in managing information acquisition, utility, retention and transfer to help a variety of organizations succeed.

Two other categories of librarians may need additional certifications, according to the BLS.

• Public school librarians typically need a teacher’s certification and some states require school librarians to pass a standardized test, such as the PRAXIS II Library Media Specialist test. This requirement varies by state and county.
  Librarians working in public libraries in some states may need certification and a librarian license.

An MLIS degree is a requirement for almost all librarian jobs in the United States and Canada. But becoming a librarian is not the only option for those holding an MLIS. Some careers that may require or prefer an MLIS degree include:

• Academic librarianship
• Archiving, special collections and records management
• Data Curation
• Database administration and development
• Digital librarianship
• Digital youth and children’s librarianship
• Information architecture and taxonomy
• Knowledge organization
• Law librarianship
• Public librarianship
• Special and corporate librarianship
• User experience

In 2024, the median annual salary for all librarians was $64,320, according to the BLS. The median salary for librarians by industry or category was:

• Elementary and secondary schools (state, local and private): $69,880
• Colleges, universities and professional schools (state): $68,570
• Colleges, universities and professional schools (private): $66,260
• Local government, excluding education and hospitals: $60,510
• Web search portals, libraries, archives, and other information services: $59,810

Many students find a rewarding career in libraries or related fields after studying graduate library science.
