# Add page number to citation, using biblatex-chicago

I'm using biblatex-chicago, and I would like to add page number in a citation separated by colon, for example, Smith (2000: 112).

Does anyone know how to do this?

By the way, with biblatex-chicago, \textcite{} is used to produce something like, Smith (2000).

You can add \DeclareDelimFormat{postnotedelim}{\addcolon\space} to your preamble, then use \textcite[postnote]{key}.

# MWE

\documentclass{article}

\usepackage[authordate]{biblatex-chicago}
