Creating a Bibliography

In Chicago style your cited sources are compiled in a Bibliography.

The bibliography should be double-spaced with a hanging indent used for each citation.

Within your Bibliography, your citations should be in alphabetical order based on the author's last name.  If there is no author listed, use the title of the source.
