The article proclaims the profundity of the field and the quality of its writers, summarizes historical highlights, defends it against its detractors, and explains the importance of helping students make informed choices by talking about books and having them available in our classrooms. The author also states his personal preferences along with his concern about the increasing length of YA books.
