Blockquote

A NOTEBOOK · EMPHASIS MINE

The block quotation is a typographic device used to designate an extended quoted passage. A block quote appears as its own verical unit and is distinguished from surrounding text through indentation, italics, type size, or some combination of these. The <blockquote> tag dates to the first draft of HTML.

In time all quotations will be properly documented, because it matters.
