What is it? The Reference section of a library is where informational books are located. Reference books cannot be checked out or leave the library. Generally people only use a section of information from a reference book, not the entire book.
Where is it? In this library…On the shelves surrounding where you are sitting. In other libraries…Look for the reference desk where a librarian will be located.
How is it organized? The call numbers of reference books have: a first line of "R" or "REF," the Dewey number for the subject covered, then the first three letters of the authors last name, or the first three letters of the title if the author is not identified.
