5.1.4 Distinguishing when to use a direct quotation instead of a paraphrase, summary, or indirect quotation
Scholars who study academic writing don't tend to talk much about rules anymore. Instead, they examine conventions that are common to different discourse communities. You can think of a discourse as a kind of conversation. Scholars in a particular field, or community, have their own understood ways of conversing that they call conventions. There is some overlap in conventions, but there are also some significant differences in the way members of different discourse communities communicate information.
