Books about books, but not the books themselves
A stupid acquisition process at the Austin Public Library results in shelving books about, say, works of Dickens, Trollope, Hardy, and many other nineteenth-century and Edwardian novelists, but a dearth of the books themselves. Our old copies of some of these are beginning to disintegrate. If you're reading something at home and not while waiting for the bus, a good hard-bound volume is better, anyhow. The entire system, according to the catalogue, has one copy of Framley Parsonage, not an obscure volume, one of the Barset series; and that copy is missing from the shelves.
