Thanks for sharing the link to the book. It looks like it has a lot of interesting information in it. I actually downloaded it to my computer for future reading. It's amazing how much (free) stuff a person can find on the Internet, if you know where to look for it.
I can see how it would be a long slow process. I hope you keep on chipping away at it, because even though it will seem like it's taking forever, it will eventually be finished, and you can pat yourself on the back for doing such a good job.
Once upon a time someone said, "slow and steady wins the race."
Sometimes that's the best way to get a big project done.
