You always need to incorporate the quotation into the flow of your essay grammatically and stylistically. You can't just copy a group of quotations and string them together with citations. You need to make them fit your own paragraphs and writing style. These examples show how you might use the same idea as a quotation or a summary. This direct quotation might supplement your own writing about paragraphs.
Many paragraphs have purposes other than topical divisions.
The same direct quotation can also be shortened to use the most important part of the quoted material. You might also add material to a quoted passage within square brackets to improve the flow grammatically within your sentence. A summary or paraphrase would also need to be cited because you are borrowing someone's ideas. You may also incorporate the author's name smoothly within the sentence and then only give the page parenthetically. You might want to do that if the author is particularly important or well known or for sentence variety.
