I found a large collection of eBooks for PDAs (Palm and PPC) at MemoWare. I am looking forward to browsing this site.

Just discovered this site -- a growing collection of literary classics, completely volunteer-driven.

I happened to run across this link recently. John Taylor Gatto's seminal work, The Underground History of American Education, has been made available online. Gatto is a former award-winning public school teacher, and this book exposes the truth about the agendas that have driven this system since its inception. It is a must-read for all parents.

Note that I am not sure if this is a permanent posting, or if it will only be up for a limited time, so take advantage while you can!
