Please take a look at GALLICA (http://gallica.bnf.fr/). Some of the articles I had put online on the holography forum used to be available at their site. In the meantime (I may have stopped looking for Lippmann resources around 2004 or so) they put a bunch of interesting books/papers touching on Lippmann photography online. I'm particularly thinking of the BULLETIN DE LA SOCIETE PHOTOGRAPHIQUE - incidentally, that journal is a real treasure for anyone interested in "alternative photography".
