Google's vision of how it intends to sell and manage our digital books in the future is pretty simple and totally sci-fi.

Google Books engineering director Dan Clancy (above right) spelled out the vision at a talk at the Computer History Museum in Mountain View last night. Here goes: Google will partner with all interested retailers, so you'll be able to buy books wherever you like—at an online site or your neighborhood bookstore. The books themselves will be stored "in the cloud," meaning out on some Google server, rather than on your computer hard drive or in a device you own. And you'll be able to read them on any device you want—e-reader, phone, computer, or netbook.

This vision is different from the arrangement spelled out in the pending settlement with the Authors Guild and the Association of American Publishers. That arrangement mostly deals with the out-of-print books Google scanned at university libraries, Clancy said, "so it's more about the past." The new vision concerns the future, in which many books will automatically launch with a digital version (as many do today) and where digital rights and licensing will be baked into publishers' business models.

Clancy stressed the importance of making it possible to buy the digital books in traditional bricks-and-mortar bookstores, as well as online.

"Right now the physical bookstores are a critical part of our book ecosystem," he said. "A huge amount of books are bought because people go into a physical bookstore and say, hey I want this, I want that. It's a mistake if we think of our future digital world as digital means online and physical means offline. Because if that happens and 10 percent of the world goes digital, that's going to be really hard for all the bookstores to sustain their business model."

Full transcript of Clancy's comments about Google's vision, after the jump.

Clancy's comments:

People look at the settlement [with the Authors Guild and the AAP] and think that that is Google's vision for what the future looks like for books. And in fact the settlement is what we figured out for these predominantly out-of-print books, so it's more about the past. And in fact we've done a lot of thinking about what is the role we want to play going forward in a digital book world, for new books.

There are [three] things we put as requirements.

One is I believe people want their books stored in the cloud.... For most people, your library is something that you don't pull books off all that often, but when you need it, you want it to be there. That's where a cloud really works. You're not going to actively manage it, but you want to make sure that five years from now, [it's there].

Number two, I think it's critical that there's diversity of choices in terms of retailers that you work with.

Now one of the things with the cloud is that the consumer needs to trust that the person who's providing the cloud will be there. So you don't trust the cloud to some new startup that you've never heard of, or some small local bookstore, that you love to go to.

But right now the physical bookstores are a critical part of our book ecosystem. And in fact a huge amount of books are bought because people go into a physical bookstore and say, hey I want this, I want that. And I think it's a mistake if we think of our future digital world as digital means online and physical means offline. Because if that happens and 10 percent of the world goes digital, that's going to be really hard for all the bookstores to sustain their business model.

So part of our model is to figure out we're going to syndicate for our partner program all of the books we sell that are new, so that any bookstore can sell a Google edition and find a way that people can buy them in bricks and mortar stores as well.

And then finally, our model is you should be able to read on any device.... Our model is some people will read [our books] on a laptop, some will read them on the phone, some people will read on their netbook, and some people will read on their e-reader. And we'll work with any reader provider that wants to make it so they can get their books from the Google cloud....

So the principles of our future world is trying to build this world where there's lots of retail players, read on any device, but it's still stored in the cloud. And as we talk with publishers and booksellers, I think this is the right model, because we're trying to make what would be an open model that encourages competition.
