When to indent your quotations

While I will likely only ever paraphrase someone in my academic writing, it is good to know the rule of when to indent a "long quotation". The rule is 5 or more lines in MLA style (Purdue Writing Lab). But wait, I learned more. If you quote even a few words in text you should cite your source immediately thereafter and not at the end of the sentence. For example:

According to some, dreams express "profound aspects of personality" (Foulkes 184), though others disagree.

And, of course, you can omit parts of quotations using the "(...)".
