Library science or library and information science (abbreviated LIS) is the study of issues related to libraries and the information fields. This includes academic studies regarding how library resources are used and how people interact with library systems. These studies tend to be specific to certain libraries at certain times. The organization of knowledge for efficient retrieval of relevant information is also a major research goal of LIS. Basic topics in LIS include the acquisition, cataloging, classification, and preservation of library materials. In a more present-day view, a fervent outgrowth of LIS is information architecture. LIS should not be confused with information theory, the mathematical study of the concept of information, or information science a field related to computer science and cognitive science.
LIS is distinct from librarianship, in a way analogous to the difference between medicine and doctoring. Librarianship, the application of library science, comprises the practical services rendered by librarians in their day-to-day attempts to meet the needs of library patrons.
