A MLS, or Master of Library Science degree, qualifies recipients to work as a professional librarian in a variety of vocational settings. Curriculum focuses on the organization, access, and preservation of information resources. This includes both physical and digital materials.

The foundational principles of the MLS degree are rooted in history, ethics, research, and practical application. Coursework is designed to examine different information systems and services, including new and evolving technology trends.

ALA Accredited MLS Programs

There are a growing number of institutions offering online MLS programs that are accredited by the American Library Association (ALA). The coursework and graduation requirements are similar to those for in-person MLS programs.

Why online MLS programs are becoming more prevalent

Some institutions offer both online and residential programs as well as hybrid models, which allow students to attend classes in-person and online. Online programs provide more flexibility in terms of scheduling and affordability. Many online programs also offer financial aid packages to qualifying students. Most importantly, choosing an online program expands your options for MLS programs since an institution's physical location doesn't factor into the decision.

To be successful in an online MLIS program, students must have reliable access to a computer, internet and email, and a quiet place to attend virtual class sessions. Most online programs require students to use specific hardware and software products to complete coursework effectively.

What is the difference between a MLS and MLIS?

There are several different names associated with Library Science degrees, but the heart of each program is very similar. Some institutions refer to their program as a Master of Library Science (MLS) while others call it a Master of Library and Information Science (MLIS) or a Master of Library and Information Studies (MLIS).

Some schools offer multiple degree programs with different library and information science concentrations. For example, you could choose between a Master of Library Science or a Master of Information Science.

Coursework between concentrations would be different, depending on your learning track. However, while curriculum between programs may vary, those that are accredited by the ALA comply with a specific set of standards and benchmarks. For this reason, most ALA-accredited MLIS and MLS programs are comparable regardless of their designated title.

ALA Requirements for MLS programs

The American Library Association (ALA) is the largest national leadership organization for the library profession in the country. The ALA provides standards and guidance on advocacy, information policy, professional and leadership development, and equity, diversity, and inclusion.

When a MLS program is accredited by the ALA, it means that an external panel has reviewed the program and determined that it meets certain criteria for educational quality. The evaluation process is based on self- and peer-assessment. Many employers prefer to hire those who have graduated from an ALA-accredited MLS program because it signals a higher level of academic proficiency. ALA accreditation is based on a variety of standards and requirements, including:

  • Standard I: Systemic Planning
  • Accredited MLS programs must have a mission, goals, objectives, and student learning outcomes. These benchmarks must be clearly stated in a public place and routinely reviewed and updated.

  • Standard II: Curriculum
  • Accredited curriculum must be based on a MLS program’s goals and objectives. Curriculum should be relevant to the Library and Information Science field. Institutions must review and update curriculum based on current industry trends and standards.

  • Standard III: Faculty
  • Accredited MLS programs must have a faculty that’s qualified and diverse. Faculty should demonstrate a commitment to teaching and research. Faculty should have advanced degrees from a variety of different academic institutions. There should be enough full-time and part-time faculty to accommodate the necessary courses and research activities available through the MLS program.

  • Standard IV: Students
  • To gain accreditation from the ALA, MLS programs must have recruitment policies that support its goals and objectives. MLS programs should be focused on providing opportunity and ensuring the success of its student body. Admission and financial aid protocol must also be clear and consistent.
