Libraries serve at least three roles in learning; firstly they serve a practical role in sharing expensive resources. Physical resources, such as books and periodicals, films and videos,software,electronic databases, specialized tools such as projectors, graphics equipment, cameras are shared by a commuity of users. Human resources, librarians( also known as information specialist) support instructional programs by responding to the requests of teachers and students and by initiating activities for teachers and students. Responsive services include maintaining reserve materials, answering reference questions, providing bibliographic instruction, developing media packages, recommending books or films and teaching users how to use materials. Proactive services include selectively disseminating information to faculty and students, initiating thematic events, collaborating with instructors to plan instruction and introducing new instructional methods and tools. In these ways libraries serve to allow instructors and students to share expensive materials and expertise (Marchionini and Maurer, 1995)
