Overview of an Online Master's Program in Library Science

A master's degree in library science provides a solid foundation of knowledge for students who want to become reference librarians, children's librarians, archivists, library directors, and information technology managers. While specific course offerings and titles vary by program and school, this information provides a general idea of what to expect from an online master's program in library science.

Common Classes and Coursework

Information Resources

This course prepares students to manage and access information collections. It covers information-gathering organizations; generation of knowledge and later storage of that knowledge; characteristics of recorded knowledge; organization and management of resources; and skills necessary to facilitate access to information in a library, school, or online.

Libraries, Information, and Society

This course examines the relationship between libraries and the communities they serve, covering topics such as ethics, intellectual freedom, intellectual property, the role of community service, and historical and international library models. Students will develop a cultural understanding and values of library systems to serve their communities successfully as librarians.

Research, Assessment, and Design

To better understand library resource management, students in this course undertake research projects and use library resources to collect, analyze, and report on results in the form of a research project.

Digital Libraries

This class provides students with the tools to understand, manage, and access digital libraries. Students may explore existing resources to understand the foundations, and they may be responsible for designing their own digital library systems. With information and library systems mainly available online, librarians must be proficient at handling digital resources.


Some programs offer students the opportunity to earn credits while gaining experience in a supervised environment. With faculty support, students may engage in hands-on work in libraries, information centers, or other professional environments related to their individual career goals.

Skills You Will Gain

By pursuing an online master's in library science, students gain skills they need for successful careers as librarians and information technology professionals. Online library science master's degree programs help students hone skills they need to succeed in the field, such as:

  • Technology Skills

    Librarians must be proficient in navigating reliable online resources to conduct in-depth research and find hard copy resources through library catalogs. Librarians must know how to navigate online databases and find obscure resources.

  • Interpersonal Skills

    Librarians help patrons with personal, professional, and educational research, often guiding people in the use of these resources. These tasks require communication and patience, which library science students can practice over the course of their master's degree studies.

  • Problem-Solving Skills

    Through conducting their own research during an online master's degree program, librarians become well-versed in research-related problem-solving. With a deep knowledge of the field, librarians have the background to help patrons with their research and provide secondary resources when a lead comes up dry.

  • Initiative-Based Skills

    Librarians must be willing to invest in continuing education, embracing new technologies and learning about how new tools can transform their organizations. By pursuing an online master's in library science, students obtain the foundations they need to embark on a career of learning.

Average Degree Length

By pursuing an online master's in library science, students gain the flexibility to work in the field while they study, racking up real-world experience while attending to responsibilities that may keep them close to home. With an online degree, students need not be limited to schools nearby, but can choose from among the best in the country.

To obtain a master's degree in library science, students complete 35-40 credits, typically spread across two years. Timelines vary depending on factors such as:

Full- or Part-Time Study

Some schools may allow expedited completion with full-time study or additional courses per term, while others may extend the timeline for part-time students.


Depending on whether a student decides to specialize in an area such as archiving, data and asset management, information organization, or school librarianship, requirements may vary.

Since some online programs charge students per term rather than per credit, expediting the degree might be cost-efficient for those who can accept a busier workload.

How to Find a Top Program

When seeking out a quality online master's program in library science, students should consider professional accreditation from the American Library Association (ALA), specializations offered, graduation rates, resources for online students, and job placement assistance.

  • ALA Accreditation

    Since most employers look for ALA-accredited programs when assessing resumes, selecting an ALA-approved program is a must. ALA sets professional standards for library science degrees and reviews programs periodically to make sure they meet these requirements.

  • Specializations

    Some programs take a general approach to library science education, while others allow students to specialize. Students should assess their career goals and carefully research available programs, discussing options with faculty and asking to speak with alumni about their experiences.

  • Graduation Rates

    High graduation rates point to student satisfaction with a program. Prospective students should seek out these figures if they are not readily available and consider factoring program retention rates into their final choice of program.

  • Resources

    Prospective students should seek out a program that offers significant resources for online students. Depending on the student's goals, these resources may include career services, tutoring, academic advising, and community-building practices that encourage distance learners to participate in some form of student life.

  • Job Placement

    Many online master's degree programs in library science offer job placement services for students and graduates. With strong career guidance in place, students can be confident that they will be placed successfully for employment when they graduate.

Additional Certifications for Library Science

While an online master's in library science prepares students for many library science careers, some states require additional certification for librarians to work in schools and public libraries. ALA also offers certification for library administrators who wish to prepare for career advancement. Though requirements vary by state, some options are listed below.

School Librarian Certification

A master's degree in library science is the minimum requirement for a career in library science, but many states require school librarians take additional steps (past the master's) in order to work in the public schools. Requirements vary, but they may include a state examination and application process.

Public Librarian Certification

Some states require public librarians to complete additional certification requirements before working in government-funded libraries. Certification may be optional, although library funding may be contingent on whether librarians and/or directors are state-certified. Most require librarians to hold a master's in library science. Additional requirements may include tests, continuing education, and proof of experience.
