Library assistants support the head librarian in operating the library and maintaining its materials. Other responsibilities include cataloging books, movies, audio resources, reference materials, slides, and microfilm. Library assistants inspect these items regularly for damage or missing pieces, especially while they are checking out resources to library patrons. As a library assistant, you must enjoy helping visitors locate materials, as well as providing technical assistance as needed. While a library assistant job does not require education beyond a high school diploma or equivalent, job seekers pursuing a career as a librarian will need a master’s degree in library science or a related field.
