Free money!

Well, not quite, but if you're a UK author, you really need to sign up at the ALCS site – once you're registered, and have added all the works that you've written or part-written, then you'll be eligible to receive payments for library borrowings, photocopying for schools, etc. Lifetime membership costs just £36, which is taken from your first payment (so no upfront cost), but you might be eligible for free membership anyway if you're a member of certain unions or other organisations.
