I'm crap at libraries too!
My Mum and a few of my friends read loads so we can pass stuff along. I buy a lot of books at charity shops (cuz they're cheap and the dosh goes to a good cause) or secondhand bookshops. This works out well as when we've all read them I can exchange them at the secondhand place for more!
Charity shops are a great place to offload books if you're moving house, they weigh a ton and are a pain in the arse to shift! I remember when I came back to UK from Germany - I had close on 800 books to move - the removal men were not happy bunnies!
