The OU courses don't do whole books (with one exception).
Sections highlighted by other readers are indicated too making the reading process less of the private, isolated affair it was in the past. John Seely Brown spoke at The OU too, so find his lecture here.
When it comes to e-learning there are a handful of must-read books, such as his one.
