Again, thank you a lot for this new amount of information.
I remember to have had some of the old "Researching & Dragona" magazines and the information they had about the Spanish army was, generally, good.
This book about the Spanish army in the Nine Years War can be also useful: "The Spanish Armies in the War of the League of Augsburg 1688-1697" by Gian Carlo Boeri, José Luis Mirecki y José Palau. Very nice, and many of the plates go into the XVIII Century.
About the web of the Catalans in the WSS, it is nice and interesting; they are taking a lot of work writing "their" History...
