Humans did not manually reformat these titles. The source was EPUB, and there was some clever automation to start. The semantic structure, internal content links, remarks and glossary entries were done essentially algorithmically. Enhancements and the ability to see code in the book were done systematically, and sometimes manually.
All of this was done using Inkling Habitat, our (as-yet unreleased) integrated content development environment. It makes this stuff much more scalable, and as we continue to roll out cool brands like O'Reilly, you'll see increasing amounts of media and interactivity where stuff like that makes sense.
