I was only able to find the two books you already found. Of course RFB&D has tuns, but that is an entirely different matter. I like to use the multiple turm search of NLS found at http://www.loc.gov/cgi-bin/zgate.nls?ACTION=INIT&FORM_HOST_PORT=/prod/www/data/nls/catalog/multipleterm.html,z3950.loc.gov,7490&CI=180729 That way I can choose more options than other searches allow. I tried several searches with it, so I'm convinced our results are just all there is. If you would be interested in resources other than books, you can let me know and if I come accross anything I think you would like I could send it to you. Off list of course. Let me know what your specific needs are if you want me to look. Sarah Van Oosterwijck http://home.earthlink.net/~netentity -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
