The Purdue Online Writing Lab (OWL)
THIS IS THE MOST HELPFUL RESOURCE EVER. I'm not kidding: my English professors were never available at 2 a.m. to answer my questions, but Purdue University's OWL always had my back. Particularly helpful are its formatting and style guides for MLA
. Regularly updated and totally free, I cannot recommend Purdue's OWL enough! Keep in mind, though: this website will not generate your citations for you.
