Kolibear I thought the contents a little odd when I saw the book. However, on reflection, I felt that the title makes LNS's point - too many people are unaware that there were just a few more types than the Lanc and the Mossie...
Anyway, any book under that title should, IMO, have:
Botha
Bombay
Albermarle
Buckingham
Hereford & Hampden
Whitley
Warwick
Windsor
Battle
Manchester
Bolingbroke
Wellesley
Stirling
Wellington
Blenheim
I'm almost tempted to say that the Halifax should be in there as well, since most British bombers of that era are now forgotten, even amongst those who have some interest in things aeronautical, I've found.
And if we're not limited to WW2 types - well, don't get me started !
