The Search for 19th Century Women Photographers

Its so frustrating searching for information on Women Photographers of the 19th Century. I've searched in museums, libraries, even the photography gallery has no information that I can find on pioneering women photographers. I have ordered a book by Naomi Rosenblum called History of Women Photographers but I'm not expecting there to be much written about Anna Atkins, Alice Austen, Laura Gilpin and others. As I say it is very frustrating and I am thinking that this could probably be a worthwhile subject to research.
