Copies of the APA 6th Edition Quick Reference handout are available at the front desk in the Penn State York library. You will also find copies of the Publication Manual of the American Psychological Association, 6th edition, and the APA Style Guide to Electronic References (since the 6th edition does not go into much detail for electronic resources, APA published this follow-up guide in 2012).

The official APA Style Blog is also a really helpful resource for specific questions.
