The Getty Conservation Institute is looking for help in creating an archive of photographic materials.

From the site:

What You Can Do
Send us samples of photographic paper and plates, film, negatives, sample books, and dated photographs. We need examples of all types of materials from every year since 1827. So, send us the box of Kodak Elite paper that might be collecting dust in your attic, that Foma film from 1985 that you think you'll never use, or the extra photographs from your 1988 (or 2006!) trip to Yosemite that didn't make it into your photo album.

We need samples that are dated and include the manufacturer's information. Even damaged materials are useful to us if they are stamped with a date and have the manufacturer's name or logo stamped on them.
