Liú Kěshū 劉可書, mid-Kāngxī Qīng official from Qīngyuàn 清苑 (Bǎodìng prefecture, Zhílì 直隸, modern Héběi). Editor of the 10-juan Fàn Zhōngzhēn jí 范忠貞集 (KR4f0017) — the collected poetry-and-prose of the martyred Fújiàn governor-general 范承謨 (1635–1676), assembled in the years immediately following Fàn’s posthumous canonization and including the imperially-composed sacrificial text, stele inscription, and shrine-tablet inscription. Liú’s editorial work is preserved as the fùlù materials in juan 9–10. No independent CBDB record under this name; Liú is otherwise a minor figure attested only through the Fàn-corpus editorial colophons.
