Chicago format is typically used in history and other humanities disciplines. There are two types of Chicago format:
The author-date style uses parenthetical citations, which means that the citation information is within parentheses beside the quoted or paraphrased information.
The note-bibliography (NB) style requires the use of footnotes or endnotes, which means that the citation information is either at the foot of the page or at the end of the article and is noted at the end of the quoted or paraphrased text with a number in superscript.
Both styles are explained in detail in the Chicago Manual of Style Online.
There are several ways to find citations using online tools. DO NOT TRUST THESE CITATIONS! Garbage in, garbage out. You should always double-check what you find to make sure it is the correct format and correct information. That being said, machine-generated citations are often a good source for the basics, such as title, author, and publication date.
