The author of the Global Sourcebook for International Data Management here. @gHosts - thanks for your comment, it's a fair one. I did write much of the basics 30 years ago - different times - and with over 4200 pages and just one author who does this for love, I do have to concentrate on certain aspects above others. I shall have a look at the gender/sex information throughout and see what I can update - a disclaimer is certainly required, in any case!
