GUI standards book?

[Eric Thomas <eathomas -at- DBITS -dot- COM>]

Hi all.
I know this might be somewhat off topic for tech-writing, but it's part of
my job right now, so I'm posting here in hope of some help.  I work for a
software company, and we need to get our GUI standards in order.  We've
decided we need to have a starting point - a GUI standards book of some
sort - which we will refer to before we make up our own standards.
Something like the Microsoft Manual of Style, but focused on the GUI.
Unfortunately, in my travels, I haven't been able to find a book that is
more "standards-based" rather than "these are ideas you should keep in
mind."  The CEO of our company mentioned IBM's old CYA manual... but I
haven't been able to find any info about that so far.  Regardless, unless I
can find an actual standards manual that makes statements similar to: "Save
is only enabled in a dialog box if a state change has taken place," then
I'm going to end up having to write one from scratch.
Any suggestions on what to look at?  I've already bought and looked at
About Face by Alan Cooper, GUI Design Essentials by Susan Weinschenk,
Pamela Jamar and Sarah Yeo, and Tog on Interface by Bruce Tognazzini - and
these are great but don't provide the hard and fast standards our CEO and
engineers want.
Thanks in advance.
-Eric
