I'm trying to use the SIGCHI LaTeX template from here


but if I try to use the \citep command It gives the error:

Undefined control sequence.

l.247 \citep

However, if I manually try to add natbib with:


I get the following error:


LaTeX Error: Command \bibsep already defined.

Or name \end... illegal, see p.192 of the manual.

How could I get \citep working?

    As bibsep was defined on line 1436 of sigchi.cls, they may not intend for you to use natbib at all. I see some exceedingly old-looking code in that class, so tread lightly with any proposed changes. – Mike Renfro Sep 12 '17 at 13:11

    The template uses numerical references, both for the Proceedings and Extended Abstract versions, so why do you want to use \citep instead of \cite? – Marijn Sep 12 '17 at 14:45

    With this document class, don't load the natbib package. Instead, load the cite package -- and use \cite instead of ‘\citep` or \citet. – Mico Sep 12 '17 at 15:20

    I'm voting to close this question as off-topic because neither does the template claim to provide \citep nor does it encourage the use of natbib. – Ruben Sep 12 '17 at 17:38
