"The Baldwin Project seeks to make available online a comprehensive collection of resources for parents and teachers of children. Our focus, initially, is on literature for children that is in the public domain in the United States. This includes all works first published before 1923."

Many of the texts include illustrations from the original book, such as Celtic Fairy Tales (1892) and The Children of Odin (1920) (but alas not The Boy's Cuchulain, which had fabulous illustrations).
