I just located a text for our last Charlotte Mason volume! Behold: https://catalog.hathitrust.org/Record/100782077
This scan contains Volume 4, books 1 AND 2! I've also added this link to the ongoing list of multivolume works, stickied at the top of the Book Suggestions forum. Volume 5 is currently in validation and will be ready for listening soon. I don't have the bandwidth at this moment to coordinate volume 4 book 2, but it is here and available for anyone who does.
Suggest and discuss books to read (all languages welcome!)
