I still have my collection of EM, Keyboard, MIX magazines, etc. They make for good reading, but are taking up too much space
Me too. Over the last year or so I've been systematically reading and ditching (where appropriate) my older issues of those same mags, including Guitar Player, Remix, etc... going back to the late 1990's. If nothing else, it's entertaining to read about the "current technology" from 10+ years ago.

So far I've gone through two milk crates and 1-1/2 filing cabinet drawers worth. Only half more to go!
But I do have some keepers from the 70's and 80s that I could never get rid of... Emerson, Wakeman, Howe, Vai, Hendrix, etc, etc. Ah, nostalgia...
