I love this site. It just might be one of the best photo history web sites on line that is not a museum. It’s a work in progress of blood, sweat and tears but progressing beautifully.
“Luminous-Lint is an online scholarly non-commercial resource that has been constructed collaboratively over the last eight years to share information on the history of photography worldwide. Over 2,300 people, estates and institutions have provided information: the website is robust, highly interconnected, and has over 10 million page views a year.”
