What we need is to encourage a culture of including references.

May I plug then {{Template:Book reference}}?
At the moment only a hundred or so pages use it. However, if the number of references using this template grows then it would become a great starting point for an automated conversion to using a references tab as mooted in other posts.
I am considering also introducing {{Web reference}} and a series of {{Journal reference}}.
