In English, our discipline is titled LIS, Library and Information Science, which in Arabic translated to مكتبات وعلوم المعلومات. But when you search the internet and the University guide book you will find the discipline is titled as علوم المكتبات والمعلومات

I dont know why the title in Arabic is not translated as it is from English ! I think its more useful and reasonable to have علوم معلومات . In the age of science and technology i think the science of libraries is dissolving in Information science.

Library science and information science are two closely-related and often intersecting disciplines that deal primarily with the organization and retrieval of information.

Library science is an interdisciplinary social science incorporating the humanities, law and applied science and studying topics related to libraries; the collection, organization and dissemination of information resources; and the political economy of information. Library science has also historically included archival science, although a conceptual distinction between libraries and archives has evolved over time.

Amongst the varied topics of study that fall within library science: how information resources are organized to serve the needs of select user groups; how people interact with classification systems and technology; how information is acquired, evaluated and applied by people in and outside of libraries as well as cross-culturally; how people are trained and educated for careers in libraries; the ethics that guide library service and organization; the legal status of libraries and information resources, and the applied science of computer technology used in documentation and records management. Library science is constantly evolving, incorporating new topics like database management, information architecture and knowledge management.

Information science (also referred to as information studies) is an interdisciplinary science primarily concerned with the collection, classification, manipulation, storage, retrieval and dissemination of information. Information science studies the application and usage of knowledge in organizations, and the interaction between people, organizations and information systems. It is often, though not exclusively, studied as a branch of computer science or informatics and is closely related to the cognitive and social sciences.
