Last week, in a stunning display of public irony, http://www.Amazon.com remotely deleted digital copies of the George Orwell novels "1984" and "Animal Farm" from customers' Kindle devices after learning that the electronic publisher of these works, MobileReference, did not have the rights to them. For a couple days, observers in print and on the Web outdid themselves, noting that in "1984," government censors rewrite history by consigning offending news items to an incinerator chute known as the memory hole.

Orwell's technological vision may have been primitive, but he seems to have predicted something fundamental about the dangers of information systems. In the wake of the uproar, Amazon announced that it would no longer use its wireless capabilities to erase readers' e-books, and Amazon Chief Executive Jeff Bezos apologized.

Lesson learned, right? Maybe, but then again, maybe not. This is, after all, the second major issue involving Amazon's control of content in the past three months; in April, "a glitch" in the company's sales-ranking feature led to the inadvertent de-ranking of hundreds of gay and lesbian books.

I don't mean to suggest that these incidents are related or that they are anything other than what Amazon claims they are: mistakes made by a company staking out the brave new world of electronic bookselling.

What is this brave new world, however, and is it the one we want?

For advocates, it's a buzzing hive of interactivity in which the solitary seeker at a bricks-and-mortar bookstore is upgraded to the collective mentality of an online "community." And yet this community can't help but operate according to its own hierarchy — a fact we confront any time a book is de-ranked or electronically deleted.

Such issues have been largely overlooked in the Amazon discussion, which takes for granted that "glitches" are inevitable and self-correcting, that the market will police itself. (We've seen how that worked on Wall Street.)

Of course, much is overlooked when it comes to Amazon, which takes our preconceptions about bookselling and publishing and turns them upside down. For those who have warned for 20 years about the homogenizing dangers of chain bookstores, Amazon is a conundrum: an independent bookstore whose ubiquity makes such distinctions obsolete.

In addition, the company has branched out beyond the traditional role of retailer, producing a piece of merchandise, the Kindle, that blurs the lines even further, functioning as both an e-book reader and a purchase portal to the store. While we're seduced by cool new technology, Amazon could be rehabbing an old structure — remember monopolies?

Meanwhile, we embrace Amazon and the Kindle with little real consideration for what it all means, as we move increasingly toward an electronic model for intellectual and literary life. Much of the talk about the digital future has to do with its inevitability, but though that may be true, it overlooks more subtle questions of engagement and control.

For Amazon, books are a business, and the more hegemony it exerts over the market, the better off it is. For the culture, though, books and information serve as a collective soul, a memory bank, something bigger than simple commerce that shouldn't be merely bought and sold.

Because of that, it's not the incidents themselves but their ramifications that are disturbing — the idea that Amazon can effectively alter the collective memory at will. The issue, in other words, isn't that Amazon has erased material from Kindles, or de-ranked gay and lesbian writers, but that it can.

This is the problem with the digitized canon and the electronic frontier: It's mutable to the point of being vulnerable.

There's always a justification — whether it be a rights issue (as it was with the Orwell books) or a programming error — but the result is the same. The collective memory, our shared informational heritage, is compromised, and we are the poorer for it, not to mention at the mercy of the very sorts of outside forces writers like Orwell have warned against.

I'm not a Luddite. I have a Kindle (although I still prefer to read on paper), and when I bought an iPod Touch, I loaded it with books. Like many people, I now live at the intersection of technology and language, ideas, "content," where we have profound new tools to move the word forward.

Still, something about its fluidity makes me wary, aware that such possibilities carry risks.

Does Amazon, as its detractors claim, want to control, or even censor, certain types of literature? As long as there's money to be made, I can't see why it would. But economics is a slippery territory, defined by self-interest rather than the public good. And that, as Amazon continues to remind us, makes for its own kind of memory hole.
