The study of library science is the knowledge of libraries, how they work, and how to catalog and search for information within the library system. A complex background in English and literature is also required. Students of this field will learn about the Dewey Decimal system, how to archive materials, cataloging, and the history and preservation of our nations' libraries. Those who learn library science can work for University and college libraries, school libraries, governmental libraries, or those classified as special libraries, meaning they are located within a hospital, courthouse, or other location. The field of library science delves into other interesting realms such as censorship laws, dealing with the general public, how to research information effectively, and organizational skills. Depending on what you choose to do with your knowledge of library studies, you can gain an important and helpful career that can bring a love of books to many people.
