I have dramatically reduced my library. In sorting and packing books I have put about 2/3 for resale, perhaps by the Anglican Christmas Fate, and just about 1/3 of them for keeping. We should have lots of space on our bookshelves.
I have also decided to jettison all my CDs and DVDs. Almost all are in my iTunes library anyway. Other music I can obtain by streaming.
There we are. The decision is taken. I do not regret it and I shall not regret it.
