A moment of amusement, from the (thankfully) long-distant past:
The Great Soviet Encyclopedia, which contains more than 100,000 entries and fills fifty-one volumes, includes some distortions so flamboyant as to be beyond belief. These are an old story. But such distortions have importance [...]
Almost everyone has heard about what happened to Beria in the Encyclopedia. After his liquidation, subscribers were notified, with full instructions, that they should snip out the article about him and insert in its place substitute articles which were duly enclosed, about the Bering Strait and an obscure eighteenth-century statesman named Berholtz. These were the best available substitutes beginning with ‘Ber’. During Stalin’s day when the party line changed on some matter so important that the Encyclopedia itself had to be changed, subscribers were obliged to turn in the volume affected to the party secretary; it was pulped and a new whole volume, cut and patched, was then sent out to the subscriber. Nowadays the reader is allowed to keep the book, and trusted to make the proper emendation himself. Progress!
Another person ‘expelled’ from the Encyclopedia was a Chinese Communist leader, Kao Kang. To replace him, a substitute page went out dealing with a city in Tibet. [...] In their haste to make the revision, the editors overlooked the fact that the same Tibetan city also appeared elsewhere in the Encyclopaedia, spelled differently.
