Accumulation blues: what to do with back issues of magazines

What, pray tell, do you do with all those magazines that build up around your house (presuming that you are, like me, omnivorous and promiscuous in acquiring them)? At a certain point, the tottering pile beside the bed, beside the chair in the living room, the jammed shelf or rack, needs to be dealt with.

And it's not as if you're no longer interested, but that even with the best will in the world, you will never again crack one of those titles; there are so many new ones following you home and building up in your office. So, what to do?

At one stage in my life, I'm ashamed to say, I had a bed propped up on pillars of back issues of Harper's. At another stage, I paid parcel postage to send accumulated magazines across the Atlantic (I know, I know).

Now, the best we can do is give the surplus to the local library to sell as its own in its annual book sale, or to a school to chop up for art class, or inter them in the blue box (to wind up who knows where?) Are there any other, better ideas for what to do with magazines that are surplus to requirements? And don't suggest not buying or subscribing to them -- we're looking for realistic strategies, here.
