I guess I solved it - finally! For some reason I had to push the first book twice in a row. Even though I had all four red dots glowing on the fourth book, indicating that everything was in order, and even though I exited and entered the library a number of times, even experiencing with pushing some buttons in light, others in darkness. If anyone else encounters this problem, make sure that you get a red dot after pushing the first book (even though it appears red on other books later).
