Here is my 3-minute tutorial of using \cite properly in LaTeX.

• Always precede it with a tilde (unbreakable space ~). This way you avoid starting a new line with a citation because of word wrapping.

  Bad:

  Garey and Johnson \cite[GJ1979]

  Good:

  Garey and Johnson~\cite[GJ1979]

• Use the optional argument (square brackets [ ]) to indicate specific part of a citation.

  Bad:

  Vazirani~\cite{Vazirani2001} page IX

  Good:

  Vazirani~\cite[p.~IX]{Vazirani2001}

• Combine multiple citations into one cite using comma.

  Bad:

  \cite{CJ} \cite{IPZ} \cite{H}

  Good:

  \cite{CJ, IPZ, H}
