Summary
A new project seeks to help identify and recover some of these films by using an online, crowdsourced platform where users can upload, tag, and comment on old stills and videos. The aptly named Lost Films contains a list of more than 3500 films it believes have been lost, and it's asking users to help provide more information.
Description
Lost Films is funded by the German Federal Cultural Association and is a collaborative effort by film societies in several countries, including Germany, France, Poland, and New Zealand, Lost Films. Anyone can join the site and can help identify the films they have in the archive or can upload clips and images from other "mystery" films as well.
