Kickstarter set up a page for projects aimed at preserving works, including a few films:
Join us as we highlight creators who are doing valuable work in looking back and shining a new light on lost or forgotten works through preservation, restoration, remastering, reprinting, etc.
Some very cool projects listed there. Oscilloscope Laboratories is $3,000 and eight days shy of restoring Kelly Reichardt’s 1994 film, River of Grass. Interesting rewards, too, like a LaserDisc chosen at random from the company’s screening library. They know their audience.
