While  checking out the sources some of you gave me about botany I
discovered these excellent sites, should anyone want to find
information quickly. Also,  U California, U Iowa, and U Nebraska had
excellent information on the MG program. UCA had excellent free
downloads on specific topics. These were well written.  It appears that
most of the states have developed their own MG program study materials,
and in the matter of publishing them, not all states are equal.

Now, on to arthropoda.

This site is a good beginning for the topic.

I guess it is just a matter of persistent searching.  Thanks again,
everyone who answered my plea. Joan
