Don't know if this is the kind of thing you want for the blog, but I'd be interested to know anyway!
Plus, I'm all for the public and the trade realising that bookselling isn't just being a shop assistant...
How well a book sells is largely to do with how much marketing budget and effort a publisher puts behind it. But booksellers seem to have a lot to do with creating "word of mouth" success for books which the publisher hasn't supported much.
Can you tell us something about what makes a bookseller think a book has that kind of potential? How do they then sell it? And how does their enthusiasm transmit through the chain and back to the publisher, to encourage the publisher to support it more?
