Huckleberry Finn - Mark Twain

Alice in Wonderland - Lewis Carroll (yep, this was banned).
The diary of Anne Frank

Possibly others. I'm not sure. All of these have at some point been ban, but some are still technically banned.
Yes, parents should screen books for their children -- it should be up to the parents, and one prays they will discern wisely.
The Church can only express which goes against Christian teaching, but the Church doesn't have the authority to ban books from the public.
There are some obvious things the Church can suggest not to get into reading, but simply ban all secular books because they are secular is extremely unwise. At some point, it could be a very good thing to get an understanding of what the secular world is doing and saying in order to combat it with truth. But I'm only talking about things that are worth reading for that purpose, like Camus or Voltaire. No point in really reading 50 Shades of Grey. Though nothing should be banned, only discouraged, even severely.
