I was at the USGS library the other day, when I came across the following
report:

	Competing Against Time
	Report to Governor George Deukmejian
        from
        The Governor's Board of Inquiry
        on the 1989 Loma Prieta Earthquake
        May 1990

It was so interesting, I called the Office of Planning and Research 
Information Center at
(916) 322-6312 to order a copy for myself.  

(you're on your own with their phone system - it took me several tries and
 an operators help to get through!)

It turns out that there is no charge for this 264  page document.
(Your tax dollars at work).
