An extremely deep and useful site for learning about the English potters (more than 1500) and potteries of the Staffordshire district is offered by Steve Birks:

Chipstone.org offers online publication of some original research reports on ceramics by names recognizable to those familiar with the archaeological literature on North America:

While a commercial site, Andrew and Olwyn as Lovers of Blue and White, offer an extremely impressive open-ended, data base project documenting English transfer ware, blue and white china, and particularly, the Asiatic Pheasant design. I might add that they are also very friendly and helpful people.
