Quantity Over Quality at Google Book Search

Campus Technology has a well-documented article about Google Book Search: The Good, the Bad & the Ugly, which suggests that Google's project is more about quantity than quality. For example, The University of California has to deliver 3,000 books a day to Google, according to their agreement. "All of the libraries are talking about that, in the sense of what might be the most interesting materials to scan. But I'll be very frank: There's a real balance point between volume and selection, especially when looking at these numbers. UC is trying to meet the needs of the contract it's signed," says Robin Chandler, former director of data acquisitions for UC's California Digital Library.

And since Google has to scan a lot of books, it needs a scalable scanning technology. "When it first started, the technical challenge was simply building a scanning device that worked. The next technical challenge was being able to run this scanning process at scale. We would have been quite happy to use commercial scanning technologies if they were adequate to scale to this. We only built our own scanning process because that was the way to make this project achievable for Google," says Dan Clancy from Google.

Surprisingly, the scanning process involves humans, as you can see in some books from Google's index (TechCrunch, Google Blogoscoped, George Hernandez, The Genealogue spotted fingers). "If you go into Google [Book Search] and look at any book, you'll be able to see by the number of body parts and fingerprints that [the pages] are being turned manually," suggests Linda Becker, VP at Kirtas, the company that produces the fastest robotic book scanner in the world: APT BookScan 2400. "If you were to go to the Google site, you'd see that one out of every five pages is either missing, or has fingers in it, or is cut off, or is blurry."

Larry Page announced in October 2007 that the book search index is "over a million books". A search for "now" returns 2,190,600 results (1,740,600 available in limited preview and 214,600 fully available for reading and downloading).

The conclusion of the article is optimistic:
When it comes down to it, then, this brave new world of book search probably needs to be understood as Book Search 1.0. And maybe participants should not get so hung up on quality that they obstruct the flow of an astounding amount of information. Right now, say many, the conveyor belt is running and the goal is to manage quantity, knowing that with time the rest of what's important will follow. Certainly, there's little doubt that in five years or so, Book Search as defined by Google will be very different. The lawsuits will have been resolved, the copyright issues sorted out, the standards settled, the technologies more broadly available, the integration more transparent.


  1. I think quantity over quality of selection makes sense right now.

  2. I don't like using the Google Book search. I tried it before but it yielded insignificant results. I just browse to open libraries in the Net.

  3. "The lawsuits will have been resolved, the copyright issues sorted out........."

    I hate to be a wet blanket, but dude Alex have you been keeping up with recent I.P. scuffs? I would love for copy write laws to be resolve within five years or so (that is, resolved in the correct way), but right now things don't look so pretty. And, the legal practice of hoarding I.P. seems to be bleeding out into the Euro cultures as well.
