I am not sure how up to date that particular page is currently (see date at very bottom left). Cloyd's Mtn been out of print for a while (and very expensive if found on the secondary market). I corresponded with the author and he unfortunately stated he has no plans for reprinting it. Instead he offers a cd version from his website: http://www.historybroker.com/items/cloyds.htm
If not great, it certainly is a good book. Definitely one of the better ones from the H.E. Howard series.
