I recently got back in touch with a friend and employer who adopted a baby from
Brazil (who is now a full grown woman!!!)and she has recommended some important resources:

The Primal Wound by Nancy Verrier (also visit her website)
Coming Home to Self by Nancy Verrier
Real parents, Real Children by Holly Von Gulden
Are These Kids Your's? which is about raising a child of a different race
Marcy Axness (adopting.org)

These are the books I have read so far:
The N word ( A great book for its expansive look at racism)
Transracial Adoptees Tell their stories (Very personal and very diverse)
Inside Transracial Adoption (I haven't finished it yet)
Black Baby White Hands ( A wonderful biography with perfect anecdotes of how a loving and educated family can make some BIG mistakes)
