If you see a book you would like to make use of please put a request on the mailing list and hopefully whoever has it will be able to furnish you with it. If not you can (in the words of the late great John Peel) go round and fart in their kitchen.
Books that are not needed, have outstayed their welcome or have been kicked out for making a mess on the carpet and chewing the furniture can be returned to Creative Spaces where they will undergo intensive retraining and will be left on the shelf until they are requested again, by which time they will have learned their apostrophes and full stops.
