I've posted this the last couple days but I'm posting again in case there's anyone who didn't see it that would like to support.
The National Recording Registry is a program run by the Library Of Congress to make a list of recordings that are "culturally, historically, or aesthetically important, and/or inform or reflect life in the United States." The recordings are then preserved for future generations.
They accept nominations from the public and in fact the number of nominations a recording receives are a very important part of the process in selecting what recordings are preserved.
If everyone on Sup Forums nominated Spiderland do you think we could get it preserved?
