Does anybody else know about Decopedia? It's an extension of Deconet which is an online marketplace for modern and mid century modern furnishings. While Deconet has a plethora of wonderful furniture for sale, unfortunately most of it is overseas.
Decopedia is a dictionary or encyclopedia for everything related to modern design. It lets you search for furniture by designer, manufacture, or browse by category. It's a great way to learn about some of the less well known designers and discover new favorites.
