A DOI (Digital Object Identifier) is a unique and never-changing string assigned to online (journal) articles, books, and other works. DOIs make it easier to retrieve works, which is why citation styles, like APA and MLA Style, recommend including them in citations.

When you include a long quote in an MLA paper, you have to format it as a block quote. MLA style (8th edition) requires block quote formatting for:
Quotes of poetry longer than three lines
Quotes of prose longer than four lines
An MLA block quote is set on a new line, indented 0.5 inches, with no quotation marks. The MLA in-text citation goes after the period at the end of the block quote.

A block quote is a long quotation, set on a new line and indented to create a separate block of text. No quotation marks are used. You have to use a block quote when quoting more than around 40 words from a source.
In APA and MLA styles, you indent block quotes 0.5 inches from the left, and add an in-text citation after the period. Some other citation styles have additional rules.
