There is no need to repeat the author's name or the title of the work if it is already clear in context. By contrast, the parenthetical citation follows final punctuation in an indented quotation. For an example of this method in action see this brief analysis of some lines from A Midsummer Night's Dream modeling the MLA style. For more detailed examples and guidelines on the MLA method for punctuating citations, see Hacker.

Organization is essential to good writing.
It is good practice to give each paragraph of your essay a mini-thesis of its own. Individual paragraphs should be as well-focused and clearly defined as is the paper as a whole. Arguments and examples that belong in one paragraph should not crop up earlier or later, in a paragraph devoted to a different stage of the argument. Coherence is essential to good writing. Pay attention to the transitions between paragraphs and between sentences within a given paragraph, making sure that the argument flows smoothly and that each paragraph or sentence picks up where the previous paragraph or sentence left off.
