There has been a lot of 'Is this a morph?' lately and I thought it might be nice to have a list of websites that can help with morph identification through pictures or text descriptions of markers and colors. I'll start with a few that I know well, but if I leave one out that you know of please feel free to add it.

NERD - One of the biggest and best breeders of BP morphs who happen to have a super gallery and pages of morph descriptions!
http://www.newenglandreptile.com

Ralph Davis Reptiles - A great breeder with a nice morph ID page.

The Snake Keeper - A nice site with a good morph page.

If anyone else has any, since I know I missed some, add away!
