Direct speech and short quotes are done with simple quotation marks, as covered in the section on special characters. Longer quotes are handled as separate paragraphs and LaTeX has two special environments for long quotes.
The first type is the quote environment, which is used for up to one line of text per short quotation. The entire quote is indented from the previous paragraph, but it has no additional indentation. The commands for this are:
\begin{quote}
Your quoted text here.
\end{quote}
The second type is the quotation environment, which is used for longer paragraphs (generally a paragraph or more) of a single quotation. With this environment, the quote is indented and the first line of each paragraph within this environment has an additional indentation. The commands for this are:
\begin{quotation}
Quotation here
\end{quotation}
