I often use Seton’s catalog as a guideline for my library list! Seton is the largest full-curriculum provider for Catholics, but there are lots of other sources. If you search on “Catholic home schooling” you’d find more books than you could ever use.
I just ordered their American History and American Literature texts for my oldest daughter. She’s “done” American history, but not in a single, start-to-finish format.
Our local Catholic school has become a nightmare. We have begged to be released from our contract. We want to homeschool and are considering Catholic Heritage Curricula. Know anything about them?
