Within days of Amazon.com‘s stock plummeting at the news of its new Amazon Prime program — offering customers severe shipping discounts — and also within days of the company upsetting Wall Street by failing to meet its fourth quarter predictions, it seems publishers, too, are upset with Amazon about something: “the way the e-tailer lists revised editions of their books on its site.” As a report on BookZonePro notes, “because Amazon uses a system whereby the first book customers see is the one with the highest sales, older editions of books tend to remain more prominent on the site, while new editions are buried under an ‘other editions’ link.” It’s “a disservice to their customers who think they are seeing the most up-to-date book,” one publisher says, but the report says “Publishers have been told that search results are operating as Amazon intends, and that the company will not circumvent the system to make manual changes.” Amazon’s refusal to fix the problem is why “some publishers see the practice as an effort by Amazon to build its used book sales since, in some cases, there are more used copies of old editions available than copies remaining in publishers’ inventory.”
