Use of references
It seems to me that the references are not needed on this page, as they are not providing any more information than is already available in the link. Thoughts? Is there a reason that these are referenced?
Agreed - we can delete the url reference links. They're no longer needed.
(Those ref links are from a legacy paragraph from the days before the first version of the wiki ==> pdf book collection extension to provide a solution for communicating the url in a print version of the page.)
