Courses in a Master's in Library Science Program

Library science programs design their own curricula. However, most programs incorporate some version of the courses listed in the sample curriculum below, including introductory classes, information science courses, and electives in a student's focus area.

Introduction to Library Sciences

Incoming graduate students in library science often start with an introductory course, which gives an overview of concentrations within library science, such as working in school libraries, public libraries, academic libraries, or other libraries. The course may also introduce students to information science.

Public Library Services

Courses that focus on public library services introduce students to the advisory services public libraries offer adult readers and children. The course may emphasize reading advocacy, organizing book talks, designing and hosting library events, and marketing skills for public libraries.

Preservation and Conservation

Library science students learn how to preserve and conserve library materials, including resources and strategies for creating a preservation policy. The course may also include archival and manuscript preservation for students planning careers in special collections or archives.

Marketing and Planning for Libraries

Library students learn how to plan and market libraries and their services. The course may emphasize strategic planning, determining short-term and long-term goals, and partnerships between the library and other institutions. Students may also complete a group project to design a marketing plan.

Government Publications

The course covers freedom of information, the federal depository library program, and sources of government information. The course particularly benefits students planning careers in academic libraries.

How to Choose a Master of Library Science Program

All library science programs share similar, overarching education goals, but when it comes to choosing a college program, the devil's in the details. Keep each of the following considerations in mind while researching your options.

Accreditation Accreditation ensures the quality of your college education. Make sure to attend a college or university with legitimate national or regional accreditation. Your library science program should also hold separate accreditation from the American Library Association (ALA), as many employers in this field consider only job candidates with ALA-accredited degrees.
Concentration Options A general library science track provides well-rounded education and training valuable to any professional in the field. However, if you have your heart set on a certain type of library work, completing a concentration is a great way to boost your employment prospects. Make sure your prospective program offers the focus you want.
Internship/Practicum Opportunities Supervised practicums are typically required for library science students who want to pursue school librarian certification. Depending on the program, other tracks may or may not require similar experiences. Decide whether or not you want to complete an in-person component and look for schools that match your preference.
Thesis Versus Non-Thesis Tracks The thesis is a unique feature of master's programs that requires students to complete extensive preparation, research, writing, and a defense/presentation. The process typically takes between 15 and 18 months from start to finish. Consider your preferences for a thesis or non-thesis degree track, and then look for schools that offer your desired option.
Cost The cost of graduate school varies widely. Annual tuition for a master's in library science can range from a low of $6,000 to more than $70,000. Librarianship is typically not a career people pursue to get rich, so it's important to choose a degree you can reasonably afford.

Master of Library Science Program Admissions

The admissions process for graduate school requires time, dedication, and close attention to detail. Prerequisites and application procedures may vary slightly from one program to another, but the following lists should provide you with a general idea of what to expect.


Bachelor's Degree: Before pursuing any form of graduate education, you typically need to earn a bachelor's degree. Your undergraduate credentials should come from an accredited institution. Bachelor's degrees in related fields like education, English, or information technology are ideal, but library science master's programs generally accept students of any undergraduate discipline. Minimum GPA: Master's programs offer a limited number of enrollment slots each year, making it vital to select students with a proven track record of academic success. For this reason, graduate schools typically require applicants to possess a minimum 3.0 GPA in their undergraduate coursework. Work Experience: Work experience is typically not a make-or-break prerequisite for a library science degree, but you will likely need to provide a resume along with your application. Prior library experience, be it entry-level work or volunteer work, may help you stand out among others in the pool.

How to Apply

Statement of Intent A statement of intent, also called a statement of purpose, allows colleges to narrow down the applicant pool to individuals who show the most promise and/or true passion for the discipline. Your statement should detail your professional goals and career interests while providing a glimpse of your character and personality.
Letters of Recommendation Letters of recommendation are a standard admission requirement for most graduate programs. Schools typically request between 1 and 3 letters. Your le recommenders should be nonrelatives familiar with your academic or professional journey. Ideal choices include undergraduate professors, managers, and coworkers. Choose writers who will reflect positively on your skills, abilities, and ambition.
Transcripts and Test Scores Graduate schools require submission of official undergraduate transcripts to confirm applicant GPA, graduation status, and details about completed coursework. Standardized tests like the GRE or GMAT are not standard requirements for library science applicants, but individuals with GPAs below 3.0 may need to provide scores from at least one of these tests.


Application Deadlines Specific admission procedures vary slightly from one school to another, but library science master's programs typically accept new students three times a year: before the spring, summer, and fall semesters. The final day to get your completed application materials submitted usually falls around two months prior to the semester start.
Test Scores If your undergraduate GPA is not quite up to par, you may need to submit GRE or GMAT scores when you apply. These standardized tests can be taken at any time, but you should plan to spend at least 1-3 months studying before sitting for the exam. Scores are valid for five years.
Supplemental Materials You should begin gathering your supplemental application materials (letters of recommendation, transcripts, statement of intent, resume, etc.) well in advance of the application deadline. Give your recommenders at least a month's notice. Request official transcripts from your school early enough to allow for processing delays.
