Informational web pages
Jim's Dollhouse Pages This is just a fabulous page, it has everything: beautiful printables, photos of projects and a finished house, a list of mistakes that can happen, lots of links, a scale calculator and even a translation service, so that the site can be viewed in different languages. It's really informative and well made.
Printable Links More printables and links to other miniature web pages.
National Association of Miniature Enthusiasts Many informative features, like hints and tips, a forum, addresses of miniature associations all over the US. Mainly interesting for Americans, though.

Actually an online shop, but they also have other informational features. Very nice (also for English speaking people) is the picture gallery. Anyone who has built a doll house, can send them pictures and they will be put in the gallery. There are some lovely houses there and by clicking on the pictures, you can get close-up views of the individual rooms.
