Suggested External Links 

I am a librarian at a large research library. I am following Wikipedia's policy "to encourage librarians and others in cultural heritage institutions to place links to their primary resources WP:CURATOR." I would like to add the following links under External Links to five historic photograph albums and sets of photographs we have digitized that contain more than one hundred 19th century images of the Yellowstone Park. 

They are in the SMU Central University Library's "U.S. West: Photographs, Manuscripts, and Imprints collection (http://digitalcollections.smu.edu/all/cul/wes)." 

You will find William Henry Jackson's Les geysers d'Amerique (26 photographs), ca. 1871-1875.
