My code is as follows:
I would like to have a : (colon) in between (year) and the (") of the title in references list. i tried using \renewcommand{\labelnamepunct}{\addcolon\space} but it doesn't work !!
<Author><year>: <Title> in: Ed by name1 and name2, place, pp. 1-90
Note: There's a space after the colon.
For example: "Hansmann, K.W. (2001): Industrielles Management,..........."
