Citation Guides

Capitalization in Foreign Language Titles

When adding a title that is in a foreign languge, follow these basic rules regardless of citation style:

For German, capitalize the first word and all nouns.

For French, capitalize THROUGH the first noun in the title.

For Italian and other languages, capitalize just the first word.

(NOTE: Always capitalize all proper nouns.)


The Author-Date System has long been used by those in the physical, natural, and social sciences. In this system, sources are briefly cited in the text, usually in parentheses, by author’s last name and date of publication. The short citations are amplified in a list of references, where full bibliographic information is provided.

Each example includes an in-text citation [T] followed by a reference-list entry [R].

If a book is available in more than one format, you should cite the version you consulted, but you may also list the other formats, as in the second example below. If an access date is required by your publisher or discipline, include it parenthetically at the end of the citation, as in the second example below.

The following examples show the more formal version of the citations. Add the date the material was last accessed for time-sensitive data or if you are required.

The following examples show the more formal version of the citations.
