I always thought they should be archived online with access for current subscribers. For as big as the magazine is, they still don't even have a website!?!?!?!?!?
I had an index running for a long time of all past issues like what you have but got behind on it and didn't feel like keeping all the old issues in storage any longer. Ended up going through all of them and making photcopies of what I liked and put them into a binder. Of course, now I have these binders to store.
