What are the rules on citing sources?
They used to be quite loose, the thinking being that it was undesirable to clutter up a children’s book with complex bibliographical material. That thinking has changed dramatically over the last 20 years or so, especially as the 1980s saw a number of folktales retold for children that were so bowdlerized the original tales were unrecognizable. With no sources, the adult consumer of this book has no way of authenticating the material. I recommend you always cite sources, whether they are print, oral or even electronic. A small print list in the back, using the Chicago Manual of Style format for bibliographies, will do.
