He can still receive books, correct? I know many "technical" books are deemed "banned" (whole other topic) but try getting some high-reviewed books on critical thinking and problem solving. Those should be able to get in. Then try to get a list of subjects the specific prison disallows. Some guards will be more lenient when letting books pass through. But if this "friend" isn't someone you would waste money attempting this on, then send him a letter with lists of books he can ask someone else to send. Try to stay away from any books with specific "labguages" and focus more on architectures and system designs.
