Well, it all depends on what kind of work you are citing. Generally you put the page or line number in parentheses after the quote. If you are only working with one quote then you can probably get away with just the page number. For example: “…It all depends on what kind of work you are citing.” (1). If you have multiple sources, you include the authors last name. I.e.: “…you put the page or line number in parentheses…” (Ashworth 1). If you don’t know the authors name, subsitute the title instead. If you are using an indirect source, film, poem or play…Well, I’d just consult a reference book for that. I’ve found “A Writer’s Reference” by Diana Hacker, is fairly comprehensive. This, or a book like it should be readily available at any library.
So many students have problems using the MLA citation style.
I believe in-text citations are called “endnotes” in the index of the MLA handbook (5th ed).
It’s pretty buried, but it’s in the manual. I’m not at work or I’d look it up.
The Harbrace handbook that many undergrads have also includes a section on citing using MLA style that is more user friendly. : )
The MLA is publishing a new edition of their handbook in May and hopefully will clear up how to cite articles found in electronic databases and web sites and an odd half dozen other issues the 5th edition addresses none too well.
