I've found dozens of good books at my local library. They weren't really all at my library, but I took in lists of books and they borrowed them from other libraries. Sometimes I had to pay a dollar for mailing expenses for some of them. A few times the librarian thought one would sound interesting and they bought a copy for our local library.
The way I made lists of books was, I went to
www.amazon.com and I searched for books with the word 'adoption'. Then I read the customer reviews (there will be a link in the left side of the page) and the ones that people like and recommended I added to my list.
Some of the ones I remember the titles of were Adopting the Hurt Child, Parenting the Hurt Child, Adopting the Older Child, Attaching in Adoption, and Real Parents Real Children. After a few dozen books on parenting adopted children, I switched to reading books about emotional problems and how to deal with them, such as The Explosive Child and The Defiant Child.
Then there were lots and lots of books and books-on-tape at the library on parenting in general , such as 'Love and Logic' (there is a book, but there are also dozens of cassette tapes about specific topics such as homework, setting limits, stepparenting, sibling rivalry, etc.), 'Raising Resilient Children', 'Raising Boys', and helping kids deal with specific problems: 'Take the Bully by the Horns', 'Mommy I'm Scared!', etc.
Now I'm starting to change to looking for books about normal child development and also different personalities of children. The book I'm reading right now is called 'Strong-willed Children or Dreamers?' and is about sensitive-creative-imaginative children.
