A new spin on getting art information. Set your preferences by city, artist, interest (including impressionism, photography and new Chinese art), venue, publications and more. The site then tailor-makes recommendations for you based on those preferences. For example, we chose Old Masters and the New York area, which yielded results that included a lecture at the Frick called Painting Desire: Parmigianino’s Antea and an article about restoring two Goya paintings. MutualArt's founder, Moti Shniberg, admits that the site is really geared towards the "serious" aficionado who approaches collecting like a real businessman. Novices might get lost in the site's endless archival vaults but you don’t have to be an expert to browse. For now, you can check it out by accessing the best version, but eventually it's going to cost you.

Best: Lots of information at your fingertips

Worst: Three hundred dollars per year for acces to the real goods.
