I would keep it for a while but you might consider checking with local historical societies and museums, they may want the stuff.
I save the special racing editions of my local paper when NASCAR comes to town. A few years ago I called the big NASCAR museum down in Daytona and asked if they wanted them. They said sure send them down. They just go into storage there but maybe it will help preserve the historical record.
LOL...that's what I say everytime I have to mess with the stuff. How long is awhile...some of this stuff is very old? Becky
