This is an inexpensive way to get your kids the classics. Hundreds of biographies, autobiographies, histories, books
of poetry, plays, and grammar, all available in .pdf format. You'll need to print these out, but you can put them in binders.
You can use the one curriculum for all your children. It's an incredible deal.
Of course, all these materials are in the public domain, so if you know what you want, you can just find them for free
on the Internet. But if you don't know where to start - if your own education wasn't full of classical literature - this is
an excellent tool.
