I can't see his argument holding water with the big stores.
I've been thinking a lot about book sales figures recently.
It's often touted that Amazon has a 40% market share in book sales, with Waterstones, WHSmith, independents and the Supermarkets etc making up the rest.
However, I don't think many debut authors get any real shelf space these days. And if they do, it's only because the publishing company is paying for it.
Simply put, the big chains only want to sell books with proven sales records. Tesco is not going to stock a debut author book without good reason.
In which case, Amazon is going to be the main outlet for new authors. It has to sell online before it hits real-world bookshelves in stores.
It's just a hunch at the moment, but I'm increasingly convinced that publishers who talk about Amazon only having a 40% marketshare are completely missing the point, because if I'm right it means Amazon has almost 100% marketshare of debut novels - and supermarkets and other chains only have a marketshare of the bestsellers.
If so, it would be misleading if anyone used the sale operations for established best sellers as a guide for selling an unknown debut.
Simply my thinking at the moment. Next time I'm in Waterstones I'm going to take note of the actual names on the SF/F shelves and see if there are any debuts, and if so, how many.
