There are a variety of different formats that can be used for citations - MLA and APA are the two most commonly used at CR, but many other specialized styles exist as well. Consult your assignment handout or ask your instructor which citation format you will be required to use.
All citation styles will require you to include important elements from your source so that the reader can find that exact same source. Some of these important elements are author, title, publisher, place of publication, date of publication. APA and MLA styles format the citation elements slightly differently. Select the tab at the top of this guide for the style you need to find instructions, examples, and a PDF handout for that citation style that you can print.
