When quoting from the text of the work you are analyzing, quote only those parts relevant to your point, working them into your own sentences grammatically. If the quotation is from a prose work, you need not preserve the arrangement of the words on the page, as it doesn't matter where the line breaks come in prose. But if the quotation comes from a play in verse, you must cite it line by line as it appears on the page, with each new line appearing on a new line of your text and any indented line indented as it is in the original. There is no need to repeat the author's name or the title of the work if it is already clear in context.

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.
