The library profession is a rewarding career path that extends far beyond the traditional image of books and quiet study spaces. Modern librarians operate as information navigators, community programmers, and technology specialists, connecting people with data and resources in diverse settings. Pursuing this career requires a specific and advanced educational foundation to equip professionals with expertise in information management and access. This specialized academic journey is necessary for those seeking professional librarian titles and responsibilities in the United States and Canada.
The Essential Professional Credential
The foundational qualification for nearly all professional librarian positions in the United States and Canada is a graduate-level degree. This standard is recognized across public, academic, and many special library settings. The degree is commonly known as the Master of Library Science (MLS) or the Master of Library and Information Science (MLIS), and it is considered the first professional degree in the field.
While entry-level roles like library assistants may only require a high school diploma or bachelor’s degree, these positions do not carry the full professional title or responsibilities. The MLIS degree is the recognized educational prerequisite for professional status, which involves instruction, collection development, and reference services. Many institutions will not consider a candidate for a professional librarian position without this specific graduate credential.
Understanding Accreditation and Program Types
The value of the master’s degree depends significantly on the program’s accreditation status. In North America, the majority of employers, particularly public and academic institutions, require the degree to be from a program accredited by the American Library Association (ALA). This accreditation signifies that the program meets the professional standards established for master’s programs in library and information studies.
The specific name of the degree can vary, including Master of Library Science (MLS), Master of Library and Information Science (MLIS), or Master of Science in Information Studies (MSIS). Despite these different names, the core curriculum is similar, covering the theoretical and practical foundations of the profession. The distinction often reflects the program’s emphasis, with MLIS or MSIS titles typically indicating a stronger focus on technology, digital curation, and information architecture.
Undergraduate Preparation for Library Science
Most graduate programs in library and information science do not require a specific undergraduate major for admission. Students enter MLIS programs from a wide range of academic backgrounds, including humanities, social sciences, and natural sciences.
A broad liberal arts education, such as a degree in English, History, or Education, is often advantageous. These disciplines cultivate strong research, communication, and analytical skills, which serve as a foundation for graduate studies. The focus during undergraduate study should be on developing intellectual curiosity and competence in critical inquiry.
Specialized Library Career Paths
The requirements for professional practice can expand beyond the foundational MLIS depending on the specific type of library setting. These specialized paths often require supplementary education or certifications to meet the unique demands of the workplace.
School Librarian/Media Specialist
A career as a school librarian, also known as a media specialist, involves working with students from pre-kindergarten through 12th grade. This path requires the standard MLIS degree combined with state-specific professional teaching credentials or licensure. Many states mandate that candidates first possess certification as a teacher or have specified classroom teaching experience before obtaining the school librarian endorsement. The American Association of School Librarians (AASL) standards guide the specialized coursework required for this educational setting.
Academic Librarian
Academic librarians work in colleges and universities, focusing on subject-specific research support and instruction for students and faculty. For many subject specialist roles within large research institutions, a second master’s degree in a relevant subject area is often preferred or required. For example, a Science Librarian might hold an MLIS and a Master of Science in Biology. This dual expertise provides the necessary subject depth to effectively curate specialized collections and partner with academic departments.
Archivist and Special Collections
Professionals working as archivists or in special collections manage unique materials such as historical documents, manuscripts, and rare books. While an MLIS degree with a concentration in archival studies is the most common path, some positions may accept or prefer a Master’s degree in Archival Studies, Public History, or a related field. University archives often maintain a strict MLIS requirement. However, non-academic institutions, such as corporate or government archives, may be more flexible, sometimes accepting a history degree paired with professional certification from the Academy of Certified Archivists.
Beyond the Degree: Essential Librarian Skills
The MLIS degree provides the theoretical framework, but successful professional practice relies on practical and interpersonal competencies. Technology fluency is required, meaning librarians must be proficient in managing digital resources, online databases, and library systems. The role has shifted to that of a technology expert who can troubleshoot access issues and navigate complex digital environments.
Customer service and communication skills are central to the profession, as librarians frequently engage with a diverse public to address their information needs. Librarians must possess strong teaching and instructional abilities to guide patrons in developing information literacy and evaluating sources. Skills in digital curation, data analysis, and metadata management are also valued for organizing digital collections and making informed decisions about library services.
The Path to Professional Practice
Earning the accredited graduate degree is the formal completion of the academic journey, but several steps remain before professional practice is achieved. Gaining practical experience through internships, practicums, or volunteer work during the degree program is beneficial for job readiness and networking. This hands-on experience allows students to apply theoretical knowledge in a real-world setting, enhancing their professional resumes.
For those pursuing careers in public schools or certain public library systems, state or provincial certification or licensure is often a mandatory post-graduation requirement. This process typically involves passing an examination and registering with the relevant regulatory body. The final step is navigating the job application process, where the combination of the accredited MLIS degree, relevant experience, and specialized certifications determines a candidate’s competitiveness.
