Geeky books

[FennelandFern]

I've been spending  lot of time reading 'The English Apple', which is a fab, if a little geeky, guide to English apple cultivars. Has anyone got any suggestions for really good geeky books about tomatoes and pumpkin growing/varieties etc etc?
This weather means I need something to keep me occupied!

My favourite geeky Tom book is Les Tomates dans mon jardin by Victor Renaud even though I don't speak French...  but Terry Marshall's Organic Tomatoes The Inside Story is quite good...  :)
