This section, new
to the second edition of this work, is intended to acknowledge those who have happened
upon this site over the years and thought enough of it to link to, comment on, or even
simply mention. Reciprocal links to their sites follow.–BPK, 6/24/2005.
Note: since this list was added in June, 2005 a number of the URLs cited have disappeared
from the web. For these sites I have relinked to archived versions, or deleted the links if
no archived version could be found.–BPK, 8/24/2012.
