Thanx to all for the kind responses. Thanx especially to darkhelmet; I usually try to acknowledge not only original authors, but also the people who dig up the quotes I use, but this time around I was so eager to cut and paste interesting snippets to my "scrap" document while I was trying to decide what I wanted to say in my letter that I forgot to make a note of the source, then I couldn't remember exactly where I'd found it. My sincere apologies for being an overeager newb!
