Data primarily from an ebook downloaded from the Overdrive library service 2020-10-20; additional data from Barnes and Noble and the Overdrive website 2020-10-24. (Although this was downloaded from a UK library using the the Overdrive service, the ebook does not appear to be commercially available from Amazon UK or Kobo (GB) as of these dates.) This ebook lacks the Lebbeus Woods illustrations that are apparently in the ibooks physical publication, although these are referenced in some notes at the end of the book. The Overdrive version (as downloaded 2020-10-20) lacks any chapter marks. The ebook listed on Barnes and Noble has a different ISBN (9781876963682) and publication date (2011-09-11), and so may be a different publication, albeit from the same publisher.
