The sheer volume of different BIM standards can be confusing in itself – and that is without even considering the  
a) usefulness, 
b) applicability, 
c) practicality or 
d) up-to-date-ness 
of these different standards

In any case, a recent and decent list has been started at:
CAD addict: List of Existing BIM Standards

Some other useful links / lists:
Weblinks (big list of Standards on natspec.org)
BIM Standard and BIM Example Drawings Sharing (forum thread)
BIM Libraries | Whole Building Design Guide
BIM/IPD Aus (standards and guidelines with Australian focus)

You may or may not already know that the Australian Revit content includes keynote files for NATSPEC.

I struggle to find keynoting settings every time.

I have previously posted about the NATSPEC BIM Portal

The Natspec Keynotes have been available since at least Revit 2010, possibly earlier:

In relation to ‘element lists’ and Revit standards, the VA BIM Guide is an expansion of the AIA Document E202 BIM Protocol Exhibit – 2008.

You can download a copy via the Web Links/ BIM Standards page of this site [downloads link inserted] (See Main Menu to your left). The VA BIM Guide is the last item in the list. Coincidentally, NATSPEC is in the process of adapting the Guide for Australian use.
