Diana Hacker (who lived and worked in the DC area!) literally wrote the book on citing sources. There is a great web resource with this information too!
Research and Documentation Online
What's that? You want a site that will automatically generate your citation in the APA or MLA format? Lucky for you, NC State Libraries (go pack!) has a tool called Citation Builder!
OR, if you don't mind some ads, Son of Citation Machine can spit out a citation for you in APA, MLA, Turabian, or Chicago style!
RefWorks!
