Internet mega-retailer Amazon is trying, mob-style, to pressure Hachette for better terms on ebooks by disappearing the publisher’s book from amazon.com.

The retailer began refusing orders late Thursday for coming Hachette books, including J.K. Rowling’s new novel. The paperback edition of Brad Stone’s “The Everything Store: Jeff Bezos and the Age of Amazon” — a book Amazon disliked so much it denounced it — is suddenly listed as “unavailable.” In some cases, even the pages promoting the books have disappeared. Anne Rivers Siddons’s new novel, “The Girls of August,” coming in July, no longer has a page for the physical book or even the Kindle edition. Only the audio edition is still being sold (for more than $60). Otherwise it is as if it did not exist.

No question about it: this sucks on Amazon’s part and demonstrates the degree to which the company’s top priority isn’t customer service. Better customer service in this case would be to offer these books for sale. I noticed another less nefarious instance of this the other day: because Amazon is offering a streaming version of The Lego Movie (which presumably has a high profit margin), they are not currently taking pre-orders of the The Lego Movie Blu-ray (out on June 17), even though Barnes and Noble has it for pre-order and Amazon has no problem offering for pre-order a Blu-ray of The Nutty Professor that isn’t out until September. I guess it makes sense to drive sales to the high-margin streaming offering but not letting people pre-order what is likely to be a very popular Blu-ray is baffling.

Anyway, if this trend continues, I’d look for Amazon to start more aggressively promoting the Kindle editions of books, to the point of manipulating available inventory as with Hachette. That is, if they’re not doing it already.
