Check out this totally amazing resource from Lambiek, the mac-daddy of European comic shops. The Comiclopedia is a searchable database of more than 9,000 international comic artists that includes both visual and biographic data.
I can imagine lots of uses for this, including checking out a customer recommendation, as a resource for students interested in the medium, and as an educational tool for new booksellers. (Pair it with :01/First Second’s awesome list of the best kids graphic novels, and it’s basically a graphic novel course in a proverbial can.)
Best of all, if you find a hole in their database, let them know, and they’ll update it.
Many thanks to Julie over at Children’s Illustration for bringing this amazing resource to my attention.
