图书信息学系，（简称图资系），旧名图书馆学系，为大学院校中的科系之一，自1992年天主教辅仁大学设立图书信息学系之后，各校原有之的图书馆学系、研究所纷纷改为图书信息学系(英译为Department of Library and Information Science)。

主要研究的学门为图书馆学(Library Science)，因应学科领域的转变，发展方向由图书服务转向图书信息服务，结合了「图书馆学」与「信息科学」，除了重视图书馆专业知识，并加信息组织服务等方面的课程。

所学习的课程内容也由图书馆为主的采购、编目、典藏、阅览方向走向信息服务为导向，包括了图书信息服务、知识管理、数字典藏、数字学习、Web2.0等。

Education for librarianship is the term for the educational preparation for professional librarians. This varies widely in different countries. In the United States and Canada, it generally consists of a master's degree program in library science. There are also bachelor's, associate, and certificate programs in library science, which provide formal training of paraprofessional library workers, library technicians, and clerks—as well as preparation for graduate study in library science.
