I have found these adoption related books very useful for understanding the psychology of being adopted, and the steps required for a search.
These links point to the books at Amazon.com.
The Primal Wound: Understanding the Adopted Child
Being Adopted: The Lifelong Search for Self
Birthright: The Guide to Search and Reunion for Adoptees
Happy Reading!

I’m actually in the midst of another one that I really like if you don’t mind me recommending it as well. It’s called The Adoption Reunion Survival Guide and is edited by Bailey & Giddens (2001, New Harbinger Publications).
Thanks for your list, and your blog!
