<<snipped>> This may require one to have a worldwide subscription. Data on a .com site is not usually fully viewable if you only have a .co.uk sub, or its local equivalent. <<snipped>> It's not the site that matters, it's the Collection-Country. I actually started with a subs to the American Collections but accessed it via the co.uk site. If you try to access UK data via the .com site, and you have a UK Collections subs, it should be perfectly possible. However, you do have to log on to the .com site first. I would be fairly confident that the .com and the .co.uk sites, along with their databases, are separate but should be mirrored as far as software and data goes. I would not, however, want to put too much money on results always being identical on both sites as new data might not have been mirrored across yet, and all your personal defaults will be different, I'm sure, on each site. If I ever log onto the .com site, I tend to log off afterwards as it once seemed to get into a knot that I suspect was due to it being unable to cope with me being logged in on both sites at once. It always worked before and it seems to work now but something went awry that time. There is, after all, very little reason to be simultaneously logged onto the .co.uk, .com, .au and .ca sites! (Same site in two different browsers, yes!) Adrian
