So very close to "everything."[1] Why don't you ask Google to put up a torrent?
[1] Anything that isn't in there is probably on a library shelf somewhere, and you're welcome to do the same thing Lexis/Westlaw did and scan it in yourself.
Certainly it will be great to have free access to the data in bulk, and that day will come. But from a practical perspective, the barrier to entry as a businessperson in this space is not data. There is enough data at https://bulk.resource.org/courts.gov/ to experiment with. And if your experiments work, there are companies that will sell you access to all the data.
Heck, that's pretty much where Lexis and West came from so long ago, but now technology is offering the possibility (at least in theory) to democratize the process so that someone can screw around with the data over a weekend or three and see if they can create something worth following up before they go through the trouble of looking for funding in order to buy data.
I don't know if we're even particularly arguing about anything. Is there really an argument to be made that this data should not be freely available? If "that day will come" then I guess all I'm saying is that sooner is better than later.
My only point was that providing open access to cases so that individuals can learn the law is a solved problem via Google Scholar. Bulk access is not a problem for individuals. I say this as someone who has worked to create better legal research tools for nearly 5 years: the first 2 on a startup that failed, the next 1 at Scholar, and the last 1.5 on a new startup that I believe will finally succeed.
So while the desire to open up PACER - and the attention given to it - is great, I don't think it will have any effect on the future of individual access to law, or to the future of innovation and business in the legal space. I don't think lack of innovation today has anything to do with lack of bulk access today. I think the deficiencies are more a reflection of the fact that innovation in this space is really hard.
Yes and no. Suppose I want to take a stab at automating Westlaw. Now I need to download all of the court opinions ever so that I can put them in my database and use them to train my machine learning algorithm. Can I actually get them for any reasonable price? All of them? And without doing something that will get me charged with unauthorized access to a computer like Aaron? Because if not, fixing that is a legitimate goal. (And if so, do post the link.)
