"We’re doing our part at O’Reilly Media to honor Aaron by posting the Open Government book files for free for anyone to download, read and share.

The files are posted on the O’Reilly Media GitHub account as PDF, Mobi, and EPUB files for now. There is a movement on the Internet (#PDFtribute) to memorialize Aaron by posting research and other material for the world to access, and we’re glad to be able to do this.

You can find the book here: github.com/oreillymedia/open_government
