For full guidance, please consult The Chicago Manual of Style Online (access for UNC affiliates via Onyen login).
Below are examples of citations as they may appear in a bibliography. The examples are meant to be illustrative and do not include every possible situation. Note that, in the Author-Date system, titles of periodicals (newspapers, journals, magazines) are capitalized as they normally are; book titles and article titles have only the first word of the title (and of any subtitles), as well as proper nouns, capitalized.
These examples don’t cover what you need? Consult the Chicago Manual of Style or contact a librarian.
