These are the standards according to the MLA version. I found this on http://honolulu.hawaii.edu/legacylib/mlahcc.html. You can find citing books and scholarly journals, and just about everything on this website. Its great. After every period, or semi colon, or any punctuation besides commas, you NEED to do 2 spaces. You need to double space your paper as well.
