I know I used to have rivers of red ink when I created reports in high school. A dropped comma, underline one source but not the other. Mistyping the proper citation format has cost me a grade or two.
Unfortunately, I have no excuse anymore. Son of Citation Machine has been help folks out of the pain of constructing MLA, APA, Turabian and Chicago styles of proper citation since 2000.
Caution - always check your schools or publication preferred citation format. You might have to make adjustments or adapt what your school requires as the proper format.
Now this might not help you on a pop quiz or the final. You are still responsible for knowing how to cite a newspaper, book, recording or web page. But if it is 3 a.m. and your paper is due at 8 a.m. you are gonna needs a little help.
