# \Cite vs. \cite

In LaTeX both the \cite and \Cite commands work and for me (using biblatex) and produce the same output.

What is the difference between the capitalized and non-capitalized version of \cite, \citauthor et.al.?

• "\Cite is similar to \cite but capitalizes the name prefix of the first name in the citation if the useprefix option is enabled, provided that there is a name prefix and the citation style prints any name at all." Quote from the biblatex documentation. For \citeauthor its the same – user36296 Jan 28 at 13:46
• @samcarter Please turn that comment into an answer, maybe with an example that shows the difference (e.g. "ibid" styles where \cite produces "ibid." and \Cite "Ibid." and names with a prefix and useprefix=true where \cite produces "van Gennep" and \Cite "Van Gennep" (vangennep in biblatex-examples.bib).) – moewe Jan 28 at 13:54
• @moewe Done! Thanks a lot for all the examples you suggested! – user36296 Jan 28 at 14:06

The difference between \cite and \Cite is the capitalization.

\Cite should make sure that the citation starts with an uppercase letter and is thus appropriate for the beginning of a sentence. Note that biblatex can only capitalise those contents of \cite/\Cite that it has control over and that biblatex is fairly conservative in its application of capitalisation macros. That means that in practice only bibstrings and name prefixes ('von', 'van', ... etc.) are capitalised automatically.

Most of the time you won't see a difference because names are normally already capitalised, but if your name has a prefix, like 'van' in the example below, you'll see the difference.

\documentclass{article}

\usepackage[style=authoryear]{biblatex}

\begin{document}

\cite{vangennep}

\Cite{vangennep}

\end{document}


Another case where this becomes relevant are styles that replace consecutive citations of the same work with 'ibid':

\documentclass{article}

\usepackage[style=authoryear-ibid]{biblatex}
