CNN has an interesting analysis of Google's attempts to digitize millions of books.

I still argue this project can only be a good thing.

The article quotes Tim O'Reilly, and while anyone who knows me knows O'Reilly and I don't see eye to eye on a lot of things, he's right when he says the biggest problem an author faces, by far, is obscurity.

I have a real-world example that I've seen firsthand. About 18 months ago, I was introduced to a pair of obscure books written by master modeler Wayne Wesolowski. Today, Wesolowski is best known for hand-building a huge model of Abraham Lincoln's funeral train, but an earlier generation knew him as someone who published articles in magazines like Model Railroader and Railroad Model Craftsman on an almost monthly basis.

In the early 1980s, Wesolowski wrote a couple of books. Both were printed twice under different titles, but one dealt with building model railroad cars from scratch and the other dealt with buildings. At the time I was introduced to them, the books were believed to be rare, and it was impossible to find a copy of either of them for any less than $125.

Today, it's still possible to buy used copies of the books for $125, but if you shop around, you can get them for a lot less. I found a copy of Wesolowski's ABCs of Building Model Railroad Cars for less than $12 earlier this month. It sold before I could click on the link, but I found another copy for $18. I snapped it up immediately.

Wesolowski's books may not always be possible to find for less than $30, but it's pretty easy to find them at or around that price with just a little bit of patience. I believe what's happening is that people who otherwise would have never known the book existed started looking for it, which in turn caused used booksellers to look for it. In the meantime, the sale of used books online has drummed up a lot of press, including in the New York Times, causing still more copies of the book to come off dusty shelves and into circulation, driving down prices and possibly driving up sales.

If snippets of text from this book were searchable online, as opposed to vague mentions on an obscure Yahoo discussion group, who knows what would happen to these books' sales? Maybe it still wouldn't be enough critical mass to ramp up publication again, but it's possible. At the very least, it'd be a bonanza for used booksellers, whether it's people who do it for a living or people who are thinning out their personal book collections.

In turn, that extra commerce can only help the economy.
