It is a curious thing that so many people only go into a bookshop when they happen to need some particular book. Do they never drop in for a little innocent carouse and refreshment? There are some knightly souls who even go so far as to make their visits to bookshops a kind of chivalrous errantry at large. They go in not because they need any certain volume, but because they feel that there may be some book that needs them. Some wistful, little forgotten sheaf of loveliness, long pining away on an upper shelf -- why not ride up, fling her across your charger (or your charge account), and gallop away. Be a little knightly, you booklovers!
