Sometime last year, I came across this list of classical education books. It has been a great resource in our homeschooling adventures. It can be sorted by grade level or author. I actually copied it (and will email to anyone interested) into Excel so that I may sort it by title as well. I love going to thrift stores, so I wanted to be able to print it out to fit into my planner and then I could look up the books as I came across them in the store.
To read a book for the first time is to make an acquaintance with a new friend; to read it for a second time is to meet an old one. ~Chinese Saying
