The Big Kiss Page is the place to go. Even though its subscription now, its a good starting point with links galore. You can still see preview images without a subscription, and it provides links to artist's pages whenever possible, so it makes it easier to find things (it is also by far the largest KiSS library on the net).
IKL has the most comprehensive list of KiSS pages anywhere. If it exists, its probably here.
My KiSS page has most of my dolls on it. It also has links to more KiSS pages you might find of interest.
