The MLA and APA handbooks provide guidance as well.
Punctuating quotations is simple, but the rules change slightly, depending on whether the quotation is documented or not.
The block format itself takes the place of quotation marks.
Once the reader knows which edition of a text you are using, the only information necessary to document a quotation is a line or page number; the format varies slightly depending on the kind of work you are quoting: For poems whose lines are numbered consecutively, from beginning to end, just use line numbers: Note too that since the parenthetical documentation must be considered part of the sentence containing the quoted material to which it refers, it must come after quotation marks but before terminal punctuation (commas, periods, and such at the end of clauses).
The ultimate test of whether a quotation is necessary or not is this question: does it help support your thesis?
Any handbook used in Rhetoric or English courses will give you an acceptable format for incorporating quotations into your writing and punctuating them correctly.Poetry quoted in this format should have the same line divisions that you see in your book.Block quotations are commonly introduced by a clause ending with a colon.Students must be careful not only to avoid plagiarism, but also to enable readers to fully understand your use of a quote or a paraphrase from a source.Never insert a quote or a paraphrase abruptly into your writing without first introducing the quote (or paraphrase), citing it, and explaining it This means that you will never begin or end a paragraph with a quote.Thus: Besides mechanical correctness, you should strive for two other goals in your use of quotations: efficiency and grace.As a rule, introduce quotations with a specific reference to their context--either events in the story, or ideas in the paragraph.Quotation and paraphrase, along with summary (which is a brief restatement of the main points of a longer work), are three ways of incorporating information from other sources into your own writing.In most writing, you should use quotations for one or more of the following specific purposes: Use quotation to reproduce distinctive, admirable, or felicitous phrasing--that is, when a paraphrase would be an inadequate representation.Never introduce a quotation with just a line or page number: Quote only as much of the text as is necessary to make your point.Don't quote several lines to establish the context of a single important line.
