Taking down the books a shelf at a time, I can see that some which I kept last year really could have gone and would not have been missed. That's good to know. They can go this year. They can go today.
It should be so much easier than last year, sorting the books! I can see me making it an annual November task. Draw the curtains on the cold wet night, switch on the lamps, pour a glass of something and work my way through the shelves.
Last year it took a week (I blogged about it from 25 Nov - 5 Dec!) this year I think I might do it in two, maybe three evenings.
