Notes and bibliography style is one of two citation options provided by the Chicago Manual of Style. Any time a source is edited or paraphrased. You can also create accurate citations using Scribbr's free Chicago Citation Generator: Chicago Citation Generator. Immediately correct all linguistic errors in your text. A Chicago-style bibliography lists the sources cited in your text. Each bibliographic entry begins with the author's name and source title, followed by the relevant publication details. The bibliography is arranged alphabetically according to the authors' surnames. A bibliography is not mandatory, but is strongly recommended for all but very short articles.
