How do I get rid of books?

[VaguelySensible]

My dc are having a clear-out, and we've got a load of old annuals (Lego, Dennis the Menace, Horrible Histories, Guinness WR etc) that nobody wants. They're from 2006-2014. Charity shops won't take them, nor car-booters, nor the school.

Suggestions?

My DS would also love second hand annuals (although maybe less so the World Record ones as he gets a new one in his stocking each year).

I'd happily take them off your hands, so definitely worth a try on freecycle. But DS has also bought second hand annuals from our local emporium of random stuff, so if you've got anything like that near you, might be worth popping in.
