The rhyme books arrive — an Old Mandarin desk, and the eastern shelves widen
30 August 2026 · Nabu news
The Chinese rhyme-book tradition is the densest phonological record any premodern language possesses: dictionaries organized not by meaning but by sound, each one a snapshot of how the language was pronounced in its century. This wave brings the tradition into the library as a connected series, verified live on 2026-08-30.
At its head stand the Guangyun (1008, 25,336 entries) and Wang Renxu’s Qieyun manuscript (17,227 entries) — the Middle Chinese standard the whole discipline reconstructs from — joined by Fujita Takumi’s restoration of the Qieyun itself (11,158 entries), the lost 601 CE parent of them all, recovered from the surviving fragments and quotations. Then the record jumps six centuries: the 蒙古字韻 (1308, 9,446 entries), the ‘Phags-pa-script rhyme book that writes Old Mandarin in the Mongol empire’s universal alphabet, and the 中原音韻 of 1324 (5,877 entries), the arch-source of Old Mandarin phonology, compiled for opera singers who needed to know what actually rhymed. The registry minted a proper Old Mandarin stage for them — no ISO code exists for it, so the lect layer now carries what the standards cannot.
Beside the rhyme books, three more doors: a Classical↔Modern Chinese parallel corpus — 14,608 chapter documents, 1.94 million passages, ~967k sentence pairs of the classical canon facing its modern rendering, the largest parallel shelf in the library after the biblical hub; the Monlam Tibetan lexicon (449,829 entries), the largest licensed machine-readable Tibetan headword list, which more than doubled the dictionary layer’s total; and DACON, the first annotated corpus of Classical Newar — Nepal’s Sanskrit-cosmopolis literature, gold-tagged — a small shelf (4 texts, 977 passages) that brought a whole language family into the registry.
Numbers as of the 2026-08-31 census; the shelves entered the catalog with the 2026-08-29/30 first syncs and were verified and wired the same week.
