See my round-up of my favorite of Matthew Reinhart's pop-up books here.
Margaret Perry is an avid reader and collector of children's literature. When she was young, at the Children's Library, she would start at "A" and work her way through the alphabet, 15 books at a time. Now she does the same thing in bookshops.
She started Little Lamb Books in January, 2009, in honor of her grandmother, to promote children's books that contain exceptional beauty in both narrative and illustration, a sense of wonder, and hopefully a touch of whimsy and silliness.
