Style sheets

Now that summer's here, I'll be coming out of the regrettable blog hibernation.

For now, I have a petty gripe: why is that some publishers insist on their own citation style but give guidelines that are about a page long? There's a reason that the common style sheets are many pages long: there is a wide variety of sources that may have specific documentation needs.

That's aside from the question of why a standard citation style sheet couldn't do.
