Classic books are such a wonderful fit for homeschooling families. There are so many different classics to choose from and sometimes it can be hard to decide what you want to use and what grade levels they are good for.
I have found a great free pdf that will teach you how to build your very own homeschool library, how to recognize classic books and how they are defined. There are huge lists of classic books that are broken down by subject matter and also by grade.
