To join a library and borrow books is free - just visit your local library or complete the online registration form.
On your first visit you will need to show proof of your signature, for example a credit card or passport. If you're under 16 you'll need to get a recommender to complete the relevant part of the form or sign a print of the online registration screen.
If you wish to use the internet the recommender must tick the relevant box. Once you've joined you can borrow from any of Ealing's libraries and return loans to any branch. Books are free but there is a small charge for audio-visual items.
