I'm having a sort out and have a some BAAF books I'm happy to post to anyone who would like them.
They're probably most suitable for prospective adopters or families in the early days of placement. The books aren't very recent - our DS has been with us for more than 10 years now - but they might still be helpful.
Books are as follows - please let me know if you'd like any of them 
Adopting a child: a guide for people interested in adoption by Jenifer Lord (6th ed, 2002)
