Dalrymple, himself afflicted from a very young age with BPD — which is a serious condition, in isolated cases fatal — explains (from 45:01) the criteria for the disease.
He who suffers from book-purchasing disorder experiences at least three of the following:
- He buys more books than 99 per cent of the population
- Book purchases amount to a significant proportion of his discretionary income
- He experiences difficulty in passing a bookstore without entering it
There are frequent episodes of BPD-associated raised tension, which can be alleviated only by purchasing another book- He buys more books than he can possibly read
- He has quarrelled with his wife about the number of books in the house
- His wife has suggested a ‘one in, one out’ policy to help him — and her — come to terms with BPD and tackle it together
- His wife has banned the presence of books from a number of the rooms in the house
