In the MLA format, "parenthetical documentation" is used to briefly identify the sources of information you have borrowed in writing your paper. Parenthetical documentation should be integrated smoothly into the text of your paper, rather than listed separately.
The general rule is to cite the source right in the text of your paper. If the reader wants to get more information, they go to the Works Cited list at the end of your paper.
If the author's name is mentioned in your writing (this is called a "signal phrase"), you only need to put the page number in parentheses at the end of the sentence. The reader can then consult the list of Works Cited (explained below) at the end of the paper to get the complete citation.
NOTE: Some sources, especially those on the Web, do not give page numbers. The general rule is to use a section number if it is given; otherwise just use the author name or, if no author is given, the first words of the title.

You may decide not to highlight the source of some of your derived information. In such cases, at the end of the sentence enclose in parantheses both the author's last name and the page referred to. The reader can then consult the list of Works Cited at the end of the paper to get the complete citation.

If possible, you should quote or paraphrase material from the original source, but if you do use material that is within someone else's work, include the abbreviation qtd. in ("quoted in") and then refer to the source where you got the information. Use qtd. in even if it's a paraphrase and not a quote.
