For Divination, I use a number of outside sources because the Harry Potter wiki doesn't go into many details about some aspects in the subject. I think that textbooks aren't a bad idea, but they should be at the teacher's discretion. For example, for Divination it might be a good idea, but it isn't really necessary for DAtDA, in my opinion.
