I can see this being a concern::
Finally, there’s the possibility that this is a ploy to create another revenue stream. The Authors Guild says that several publishing sources have surmised that “Amazon is attempting to coerce publishers into using its print-on-demand (POD) services.” Amazon’s thinking is that, if a book were to unexpectedly go out of stock, then it could be printed immediately, essentially solving the whole stock problem. (POD, Amazon has argued, would also increase delivery times.)
:: However I can't help thinking that it's another case of the Traditional Publishing paradigm having problems coming into the new century.
For some background:: As a POD publisher I was interested in going to B&M Barnes and Noble locally and doing some promo of my book. Presently what that requires is to use a local traditional printing house and purchasing a truckload of books[or coming up with a feasible business plan that will get the printing house to bend their rules] if they were already doing POD then I could have just ordered what I needed--or what I thought I needed.
So how does this fit the amazon bid::
Easy they already have infrastructure for the POD. They get electronic files from from publishers and send them to their POD printer. They do a large volume of business with them so they can easily order 10 copies per run; because the system is setup that way. The only possible problem with this is if accountability gets muddled, which I think is a current valid argument. They would have to have a system whereby whenever a specific book is printed that the POD publisher gets a full accounting of numbers. [This is where I have my concerns because there are more used books available for my titles than were printed according to the accounting system.] So there is that. But I don't think that's a major issue.
None of this means that the traditional avenue needs to totally change what they do. They could still require stores to order X number initially. They could even use their own POD printer to distribute from; though it might become more feasible to have a printer close to the target location or even allow the stores to have their own appointed POD printers. There would just have to be that bit of accountability. And if they force a print of X number they would still have to offer some return policy in the mix for any store that can't sell that number. So things don't change too much in that area depending on how much the publisher wants to change.
That much said what this does on the benefit side:
It means that the book can continue to be available because it doesn't rely as heavily on the old model of single large runs that may never be repeated if the sales are not there. POD allows it to be available because it allows for single unit to be printed.(Although I seriously doubt that that happens, it's likely to be that if they need more to fill an order they will have a minimum run and fill inventory.)
I think amazon is making perfect sense in that they can reduce the need for excess stock and concentrate on pulling what they need from the available POD printers.
I think that if they make it work and get enough traditional publisher involvement, that it could change the face of publishing[Finally].
