I don't know if it is appropriate to publicize a book one of the list serve members wrote but I will take a chance and give you information about mine. Although the book is about U.S. photo postcards in general there are many examples of New York State views and discussion about NY postcard photographers. This is the third book I have done on photo postcards. The other two are on Adirondack photographers.
 
Below is a link to the book (Real Photo Postcard Guide: The People's Photography, Syracuse University Press). It is for state and local historians, photo historians, postcard collectors, and ephemera dealers. Double click for detailed information on how to get a copy. http://www.syracuseuniversitypress.syr.edu/email/real-photo.html <http://www.syracuseuniversitypress.syr.edu/email/real-photo.html>  <http://www.syracuseuniversitypress.syr.edu/email/real-photo.html <http://www.syracuseuniversitypress.syr.edu/email/real-photo.html> >
