Maybe this doesn't warrant its own thread... but I know Iwould have missed it had it been in one of the General threads.

You might be able to get one of these as a free book joining audible.  My Dad buys audible credits by the doubledozen, so each one for him is $10.  I convinced him to sell me 2 credits to download these for me since the old tape abridgments are so aweful.

It's a bit of a trick to get them off of audible, but I made it work.  I found some instructions online which said to use Nero 8,9, or 10 (later versions don't work) and to use it to 'burn' an Audible audiobook.  Then change the burner to a virtual burner and you get 15 or so isos.  Then mount the isos one at a time and rip with your favorite ripping software. 

You could do the same with 15 or so real discs for each book, but why when you can do it this way.

I haven't listened to them yet, but I will soon.
