After retrieving the ebook Andersen's Fairy Tales I looked at the related information and tools.  I think the section "Back in Times" is fun to check out since it gives some details about various children's literature that was popular or written during different years.  For example, in 1941, during the war many of the children's books contain war themes.  The historical perspective is interesting to look through.
