Secular Charlotte Mason

This is a book list I found and saved to help guide me a bit in some choices for our reading.. click here: Charlotte Mason Books I have not gone through all of them but it seems it is a pretty comprehensive listing.

Not completely secular, but a very nice list non-the-less. I like how it is organized. I have used many of those books in our homeschooling.  I think my youngest may like that monthly approach the author describes. Where did you find the list?
