Choosing the Right Master’s in Library Science for Your Career

When deciding between a Master’s in Library Science and a Master’s in Library and Information Science (MLIS), understanding the differences and unique benefits of each program is essential. While both degrees prepare students for careers in librarianship and information management, their focus, curriculum, and career applications vary slightly. This guide provides a comprehensive comparison to help prospective students make the right decision based on their career goals and interests. However, it’s important to note that these degree titles are often used interchangeably, and both will lead to a broad spectrum of librarian careers.

What Is a Master's in Library Science Degree?

The Master’s in Library Science is a traditional degree designed for students pursuing careers in public, academic, or school libraries. The program focuses on foundational library science skills, including cataloging, reference services, collection management, and literacy programming.

A Master’s in Library Science degree emphasizes the practical aspects of librarianship, preparing graduates to work directly with communities, students, or library patrons. Coursework typically includes subjects like information organization, library management, and user services. Some programs also offer electives in children’s librarianship or public library administration for students who want to specialize.

Key Features of Master’s in Library Science Programs:

Core Focus: Foundational librarianship skills like cataloging, resource management, and reader advisory services.
Career Paths: Public librarians, school media specialists, and academic librarians.
Best Fit For: Students interested in traditional library roles with a strong emphasis on community and educational services.

What Is a Master's in Library & Information Science Degree?

The Master’s in Library and Information Science (MLIS) degree often expands upon traditional library science principles by integrating information science and modern technologies. MLIS programs prepare students for a wide range of careers, not just in libraries but also in digital archives, corporate information management, and specialized sectors like healthcare and law.

This degree emphasizes technology, data, and digital resource management. Students often delve into areas such as metadata, user experience design, and digital curation. Many MLIS programs also offer specializations, including digital libraries, archival studies, law librarianship, and records management, making it a versatile choice for students seeking broader opportunities.

Key Features of MLIS Programs:

Core Focus: Digital information management, metadata, and emerging technologies in information science.
Career Paths: Digital archivists, corporate information managers, and specialized librarians in fields like law and healthcare.
Best Fit For: Students interested in advanced technology integration, data science, or information governance roles beyond traditional libraries.

Library Science Graduate Degrees: Key Differences

While both degree titles share foundational elements, they can diverge slightly in focus, curriculum, and career applications. It’s always advised to review the curriculum and focus of the degree programs you are considering to make sure they align with your goals, regardless of title.

The curriculum for MLIS programs typically includes advanced topics like data science and digital archiving, preparing graduates for roles in technology-driven fields. Master’s in Library Science programs tend to remain more focused on traditional library functions, though both degrees share foundational library science coursework.

Choosing the Right Degree for Your Goals

Deciding between master’s degrees in library science depends on your career aspirations and interests, though both degrees will qualify you to work in most library settings.

Consider a Master’s in Library Science if you:

Aspire to work in public, school, or academic libraries.
Prefer a traditional role focused on literacy, community service, and educational programming.
Value direct engagement with patrons and resource management

Consider an MLIS if you:

Are interested in digital archives, corporate roles, or information governance.
Want a career that combines technology with information science.
Plan to specialize in niche fields like law, healthcare, or records management

Employer Perspectives on Graduate Library Science Degrees

Both Master’s in Library Science and MLIS degrees are widely recognized and respected by employers. The choice between the two typically comes down to the specific job role and the skills required. For traditional library positions, a Master’s in Library Science is sufficient and highly regarded. However, for technology-driven roles or specialized positions, employers may prefer candidates with an MLIS due to their training in advanced information science and digital tools.

Master's in Library Science vs. Library & Information Science Degree Education Pathways

Both degrees offer valuable pathways to rewarding careers in library and information science. While the library science degree focuses on traditional librarianship, the MLIS provides a more versatile education that extends into emerging fields. Prospective students should consider their career goals, interests, and the evolving demands of the library and information science profession when choosing between the two, though it’s good to remember that there is generally little difference between them.
