Both books fit well with the other BabyLit books in the series. I love that they are board books. In Treasure Island the child is introduced to the characters in the classic story Treasure Island while learning about the different shapes such as finding the oval in Long John Silver's eye patch. In Emma the child is introduced to the characters in Jane Austen's classic story along with their emotions such as "Harriet is sad."
Each book is "printed on either recycled, 100% post-consumer waste, FSC-certified papers or on paper produced from sustainable PEFC-certified forest/controlled wood source." If you are into that kind of thing they are environmentally friendly I guess. For more information on that you can check it out at: www.pefc.org
As I mentioned, these books are board books. They are of good quality, thick and durable. I love BabyLit books for the fact that you can introduce even the youngest members of your family to the timeless characters in each story while helping them learn about emotions, shapes, numbers, etc.
