Haven't even started the project yet and already I've found out something that I didn't know. Back when I started this I thought that the e-book arrangement would give virtually free classics to anyone that wanted it. Not quite. Most of them were free on the Kindle but very few were on the Nook. Barnes and Noble are selling most of these for a dollar or less. Google books had all of them but the formats can be a bit wonky. I might go back and set up links to Project Gutenberg at some point too.
It's something of a modern cliche to note that we have tremendous amounts of knowledge at our fingertips. Setting this up really drove that home for me.
