A library is more than just a place where books are stored. A library is a source of information. The information may come from books (fiction , nonfiction, or reference book), from periodicals (newspapers, magazines, and journals), from audio-visual materials (records, cassettes, microfilms, video tapes, etc.), or even from a computer terminal. Students go to libraries to study and write research papers. The periodicals room of a university library is where foreign students often find newspapers and magazines from their countries . In the reference room, they can find catalogs(目录) from many universities in the U.S. and other countries. If you are buying a used car, the reference librarian can show you the Blue Book which lists the prices of new and used cars. People who need information in a hurry can telephone the reference librarian at many libraries. There are as many different library services as there are types of people who use them. Children’s libraries provide materials for young readers. They sometimes have storytellers who read stories to groups of children , and a few have computers for the children to play with. Music lovers can listen to recordings of their favorite musicians in music libraries . Some libraries have painting and sculpture exhibits, and most libraries offer special services for blind people, such as books in Braille, ―talking‖ books , and Kurzweil Reading Machines. Libraries provide entertainment as well as information. Novels and short stories from a library’s fiction collection are a good source of enjoyable reading practice. Public libraries often sponsor lectures on topics of interest to member of the community, and a few even offer concerts and films.
