Question

How do you know when to use block quote vs. a short quote?

How many spaces is a block quote indent?

Where does the citation for a block quote.

Answer 1

You use a block quote when the quote is longer than 4 lines. The indent is the same same as a standard tab.  This is for MLA format

Answer 2

When you type it up on the computer, if the quote takes up 5 lines or more, you need to block quote it. The citation goes at the end of the quote, just like any normal quote, except you don't have to worry about actual quotation marks. The indent is 10 spaces.
