Spent some time today updating the SF Artists wiki, based largely on the Locus online index of covers. I have not entered all the artists who published book covers this year, but I hit my favorites and those who were most prolific. Kudos to Donato Giancola, the first artist I have seen who actually put a simple text chronological list of his works up on his website (oo, Timothy Lantz did it too).
Artists I found particularly interesting while doing this include:
Rick Berry, whose cover for Neuromancer is said to be the first digitally-painted book cover ever done.
Greg Bridges, who seems to have come a long way since his early work.
Dan Dos Santos, who has a rich, colorful, yet clean and detailed style no doubt highly influenced by comics, and who offers painting tutorials on his website.
Saara Salmi, who does digital photo-composite artwork that reminds me a bit of Dave McKean, as well as other illustration.
Raymond Swanland, who was one of the primary artists of the Oddworld video games, and has also done some rather nice book covers.
