Zhāng Xuàn 張鉉 (fl. ca. 1328–1344), zì Yòngdǐng 用鼎, sometimes self-styled Fúguāngshì 浮光士. Yuán-period scholar, writer, and educational official. The Sìkù tíyào describes him as “a man of Shaǎnxī”; the prefectural correspondence in the Xiūzhì wényí of the Jīnlíng xīnzhì refers to him as “Shaǎnxī rúguān 陜西儒官 Zhāng Yòngdǐng — a name elderly and well-formed (lǎochéng 老成), whose literary diction is canonical and elegant; without him the work cannot be brought to completion.” He served as shānzhǎng 山長 (Head of Studies) of the Xuégǔ shūyuàn 學古書院 in Fèngyuánlù 奉元路 (modern Xī’ān) before being summoned to lead the compilation of the Jīnlíng xīnzhì.
By his own report (in his Xiūzhì běnmò), he had spent more than fifteen years residing in Jīnlíng / Jǐqìnglù as a private tutor before being officially invited; the prefectural authorities sent the prefectural judge Zhōu Yáo 周垚, the school jiàoshòu Zhōu, and the Mìngdào shūyuàn shānzhǎng Fáng to his residence with ceremonial gifts (Zhìzhèng 3 / 1343, fifth month) to invite him formally. He completed the Jīnlíng xīnzhì (KR2k0027) in six months between summer and winter of 1343, and saw it through the press in 1344. The work is regarded as one of the finest Yuán prefectural gazetteers and the foundational record of late-Yuán Nánjīng on the eve of the Míng founding. No CBDB id confidently established (multiple Zhāng Xuàn entries in CBDB; none with floruit specifically aligned to 1343 in northwestern China and Jiāngnán).
