Earlier today, I wrote about the debates Wendy and I had when merging our book collection, and mentioned that Wendy likes to keep copies of different editions of the same book, and – in some cases – duplicates of the same edition of the same book. This picture sort of illustrates the point… though I know we have at least two other editions of the Oxford Handbook (5th and 8th) and more BNFs around the place than I could lay my hands on for this photo…!
