When Philipp Lenssen started writing Google Apps Hacks, we made up our minds that we’d develop the book in Google Docs. A while back, Philipp wrote up Part I of the story of how we made the book. From Writing a Book in Google Docs:

Currently, my editor Brian Jepson and I are collaboratively writing the book (tentatively titled) Google Office Hacks by O’Reilly using Google Docs. I wanted to outline the process we came up with, and maybe it’s helpful for you too for certain needs.

I just wrote Part II of this story, and Philipp’s posted it to the Google Blogoscoped blog. From From Google Docs to InDesign:

One of the tricky parts for us was getting the chapters into InDesign, the book layout program we use for our books and magazines. I know where we were coming from – Google Docs’ HTML format – and where we were going to – InDesign’s tagged text format.
