At this point you've done a lot of reading on-line, and you have a good idea on how Lovelace is organized. You're welcome to continue to use the on-line version, but I recommend buying the book instead. There's enough material left that it'd be faster to use the book version than the on-line version. So, if you'd like to buy the book, more information about the Lovelace book is available.
