My thanks to all who weighed in on this inquiry with thoughtful and sensible
comments.  Here's what I've decided to do:

I am going to purchase the requested books - they are both out of print but
available for a few bucks on Amazon.com.  Declining to purchase them after a
specific request has been made is not a battle worth fighting.  I do have a
handful of general management / leadership philosophy titles, so they will
go in there.  BUT because of the requested books' explicitly evangelical
Christian viewpoint, in accordance with our stated commitment to cultural
diversity and nondiscrimination, I am also going to purchase a few
additional titles (also available for about $10 each) to accompany them:

Beekun, R A: *Leadership: an Islamic perspective* - ISBN 9780915957941
Metcalf, F: *What would Buddha do at work?* - ISBN 9781569753002
Zweifel, T: *The rabbi and the CEO* - ISBN 9781590791509

I am being flexible in response to a patron / administrative request,
offering a variety of resources on a particular topic, and assuaging my own
discomfort for less than $50.  And if anyone ever comes to read any of them,
perhaps they will be "enlightened."

Namaste!
