Print copies of 6th edition of the Publication Manual of the American Psychological Association are available in the Reference Collection on the library's main floor.
There are a number of open source software managing tools that can help you organize your research and generate citation for both scholarly and print sources. In addition to Zotero, we recommend any of these programs.
The Carmichael Library has the hard copy guide to each of the major citation schemes, including the big three: MLA, APA, and Chicago. Please refer to these printed books, located on the first floor in the reference collection, if you have questions about writing and citing with these formats.
