[Tex/LaTex] Using square bracket in text mode


I would like to include text like the following in a latex document [2007] EWCA Civ 1042.

Unfortunately if I use \[2007\] EWCA Civ 1042 the number within the square brackets is typeset on a separate line. \[ must mean something I don't know. How do I escape a square bracket?

I realise this may be a stupid question, but the only way to escape things I know of is backslash.

Best Answer

You don't escape square brackets in LaTeX if you want them typeset. \[ and \] are basically synonyms for \begin{displaymath} and \end{displaymath}, (or \begin{equation*} and \end{equation*} with amsmath loaded), and will make the enclosed content typeset in a unnumbered displayed math equation on a separate line, which is clearly not what you want.

In conclusion you should simply write

[2007] EWCA Civ 1042

verbatim to get the output

[2007] EWCA Civ 1042

Edit: As noted in the comments, this will not work in the special cases where the brackets follow a macro (as in \item [2007] EWA) or if it comes first in a row in a tabular. In these situations one should group the brackets inside braces as {[2007]} EWA.
