Chicago is most commonly used in history and humanities. There are two systems of citation in Chicago, Notes & Bibliography and Author/Date. If your professor hasn't specified, footnotes are the most common usage.
If you feel nervous about citing sources on your own, Zotero is a great resource that works with your web browser to collect information about your sources and with your word processor to format citations automatically. As with any program be sure to check the information and formatting Zotero pulls in before inserting it into your paper.
Quick start to Zotero:
More detailed instructions are offered in the Zotero Guide.
Chicago short-title citation: when you cite the same title more than once, you may use a shortened form after the first full citation: surname(s) of author(s), shortened title, page number [if available].

Same as book, but add source of online edition or eBook. Electronic sources do not always include page numbers, so it may be appropriate in a note to include a chapter or paragraph number (if available), a section heading, or a descriptive phrase that follows the organizational divisions of the work.

No bibliographic entry is required for photographs. Put all required information in the footnote or text.
While each professor may have a different preference for what information you will need for an image citation, you can use this as a guide.
If you do not know any of these items, provide what you do know and put “unknown” for the rest.
Sometimes, it is sufficient to give just a credit line below the image, rather than a full footnote or endnote. Generally, Turabian style does not require a bibliographic citation for an image.

An annotated bibliography includes a citation and a written statement or abstract about each work to help potential readers decide if an item is relevant to their interests.
