These are a great series of books. I bought four different ones for xmas presents and they went down really well; would be good for either adults or older children who want a basic introduction to a subject. They are accessible and cover a lot of ground. If you feel pretty ignorant about a subject, this is a good way of getting a feel for the basic terms, concepts, etc. Having said that, one of my children is doing politics A-level (so should already know quite a bit about the subject) but has read the politics version and also thought it was great. They also look really nice and are well presented - so make good presents.
