I've already mentioned the Verna Aardemas specific books whcih I used in this web page as well as some additional ones for further reading. The biography page that I wrote came from an article I read months ago, but could not re-locate.
Corel Print & Photo House CD was used for the Iguna picture.
Picture of Verna Aardema came from internet site. Additionally, there is a link to that internet site on the Biography page. Http://ocean.st.usm.edu/~dajones/findaids/aardem.htm
