Chicago Style actually consists of two citation styles: Author-page style and note-bibliopgraphy style. The author-page style is similar to MLA and APA citation styles in that it includes in-text citations that immediately follow the material you are referencing and a list of reference at the end of your paper. The note-bibliography style differs in that your in-text citations appear in footnotes at the bottom of each page or endnotes at the end of each section. The note-bibliography style includes a list of all references at the end of your paper, called the Bibliography. You should ask your teacher which of these styles you should use!
The library has copies of the following books that can walk you through Chicago citations from start to finish.
