For many years I consulted, often several times daily, the extensive list of artists' names called Commanducci after the Ottocento expert Agostino Mario Comanducci (1891-1940). It was a secret I shared here several times, as it combined extremely handy features with simplicity and comprehensiveness. Now it is off the air. Had it been a paysite, I would gladly have subscribed as I do Artprice. But it wasn't, it was free and not widely known. What a pity it is no longer available.
What do you all use as first tool to identify an artist?
