It looks bigger than it is, so I wouldn't have made any page challenge with those, I think. :D There's a lot of veeery trashy stuff on there- all the tell-alls, the German classist comedy literature, and the comedy books aren't really that big, so.

And as far as I'm concerned, the Silmarillion is three books at least. Though I'm biased, since I never made it past page 20 or so.
