Library instruction, also called bibliographic instruction, user education and library orientation, is the process where librarians teach their patrons how to access information in libraries. It often involves instruction about research and organizational tools and methods. It prepares individuals to make immediate and lifelong use of information effectively by teaching the concepts and logic of information access and evaluation, and by fostering information independence and critical thinking. Above all they are aimed at equipping library users with skills to locate library sources and use them effectively to satisfy their information needs.
