From Charles Lamb’s Detached Thoughts on Books and Reading:
In this catalogue of books which are no books—biblia abiblia—I reckon Court Calendars, Directories, Pocket Books, Draught Boards bound and lettered at the back, Scientific Treatises, Almanacks, Statutes at Large; the works of Hume, Gibbon, Robertson, Beattie, Soame Jenyns, and, generally, all those volumes which “no gentleman’s library should be without:” the Histories of Flavius Josephus (that learned Jew), and Paley’s Moral Philosophy. With these exceptions, I can read almost any thing. I bless my stars for a taste so catholic, so unexcluding.
I confess that it moves my spleen to see these things in books’ clothing perched upon shelves, like false saints, usurpers of true shrines, intruders into the sanctuary, thrusting out the legitimate occupants. To reach down a well-bound semblance of a volume, and hope it is some kind-hearted play-book, then, opening what “seem its leaves,” to come bolt upon a withering Population Essay. To expect a Steele, or a Farquhar, and find—Adam Smith. To view a well-arranged assortment of blockheaded Encyclopædias (Anglicanas or Metropolitanas) set out in an array of Russia, or Morocco, when a tithe of that good leather would comfortably re-clothe my shivering folios; would renovate Paracelsus himself, and enable old Raymund Lully to look like himself again in the world. I never see these impostors, but I long to strip them, to warm my ragged veterans in their spoils.
I’ve linked to my best guess at the forgotten authors mentioned (the Penguin edition editor conveniently fails to identify them). Lamb is of course having half – or better – a joke but it’s fitting that two centuries on no one reads any of the authors mentioned except fragments of Hume and Gibbon. And for Hume no one is reading the work that context argues he’s being cited for here – his History of England.
