My own RAH
collection stands at 34 books, including all the juveniles. I started reading him early, and still pick up the odd copy in second-hand and charity shops.
The only major books that I still haven't got are Jonathan Hoag
, Farnham's Freehold
and Sixth Column
- for some reason these don't turn up at all.
Perhaps people just don't get rid of them once bought.....
