Judith:

This isn't a tip, but a request instead.  For students, of course,
learning these strategies and tricks for searching is easier with
examples from specific collections. For our teachers, using the
mini-units would be oh so handy in our American History classes for those
examples to be chronologically ordered.

At the moment we're fighting the Revolution; we're writing the Constitution
about 10 days from now; and we're fixing to buy some land west of the Miss.
next month.  We'll jump on any search exercises that tie into these early units.

Thanks,
George West
