I'd just like to say this is the most polite group of researchers I am tickled to work with.... if someone posts a webpage address they are thanked. The library list I posted last night has generated no less than 6 thank yous. One to the list and 5 to me personally. Thanks guys. Nice to work with you! When school lets out this year I hope to be able to help more. And thanks to the lookup volunteers recently --- please imagine us collectively giving you a dozen red roses! What a task! Cynthia
