Center the words "Works Cited" at the top of the page. Double space between works only. Use a hanging indent of .5" (1.27 cm). Alphabetize by author's last name.

Incidentally, knowing how to do the actual citations is a good idea, too:

To cite a direct quote in-text:
  "Quote" (Authorslastname PAGENUMBER).

For example:

  "Maybe we should just have skipped from 1967 to 1969" (Barry 128).

To cite a paraphrase:

  Paraphrase (Authorslastname PAGENUMBER).

For example:

  1967 sucked (Barry 128).

On the Works Cited page:

  Authorslastname, Authorsfirstname.  Title of Work.  City: Publisher, DATE.

For example:

  Barry, Dave.  Dave Barry Turns 50.  New York: Ballantine, 1998.

There are a hell of a lot of rules for books with no authors, two authors, editors, magazines, websites, etc. I'm not going to put them all here.

  Authorslastname, Authorsfirstname.  "Title of page".  <url> (Date you went there).

The author's name is omitted if not given--alphabetize by title. For example:

  "Welcome to Everything@Everything2.com."  <http://www.everything2.com> (Jan 1, 2001).

For a magazine:

  Authorsfirstname, Authorslastname.  "Title of Article."  Magazine, Date, PAGES.

For example:

  Tarpy, Cliff.  "Danube River."  National Geographic, March 2002, 62-79.

For these examples, the Works Cited page will look something like this:


Works Cited

  Barry, Dave.  Dave Barry Turns 50.  New York: Ballantine, 1998.

  Tarpy, Cliff.  "Danube River."  National Geographic, March 2002, 62-79

  "Welcome to Everything@Everything2.com."  <http://www.everything2.com> (Jan 1, 2001).

I'd pay good money to see the report that went with that!
