Books are the basic tools of libraries.
   
They can teach you how to build something, why people behave a certain way or how to find help with a problem. They inform and entertain. And they can give you the past, present and the future.
   
Typically a book has:

• a cover and preliminary pages (title, dedication, table of contents, list of illustrations, preface and/or introduction)
• text, graphics and notes
• auxiliary materials (glossary, appendix, notes, index, works cited and/or bibliography)
