I am an author.
I owe a lot of my early success to my local independent bookshop. They have just been nominated Independent Bookshop of the Year. They've already won many awards.
They work extremely hard: I have had emails from them at all times of the week: late on Sunday night, before breakfast on weekdays, etc. They run a lot of events.
One of the things they have to compete with is the browsing-in-shops-but-buying-at-Amazon customer. Please buy books from your indie, too, don't just browse.
Please, also, don't buy 'new' books from Amazon Marketplace. There are lots of reasons for this. The new books on offer here are often the review copies that authors' publicists send out in the hope that the books might receive some column inches in the few remaining print review sections. If you buy a new book from there (second-hand is a whole other subject for another post) the author won't receive a single penny for their work. So they haven't got a review and they've lost a sale.
If my books hadn't been on display on shelves I wouldn't be slowly building a readership.
Publishing is a hard, hard business for the indies and the chains and for authors. I can only survive as an author if new copies of my books are available in shops. I take my hat off to the good indies: they are helping to keep some authors in business.
Perhaps it would be no loss to literature if I packed up my writing. But enough of us give up and take on well-paid jobs elsewhere there will be no replacements for the big names ten years down the line. Authors earn very little on average: around £7000 would be considered good.
