清代經學大家朱鶴齡(1606-1683)於明清鼎革後專意著述，終生未曾仕清。但他望重士林，著作入選《四庫全書》之集部類國朝著錄書中。在被認為有「寓禁於徵」目的之《四庫全書》修纂工程裡，朱鶴齡能以「布衣遺民」的身分入選，實別具指標意義。朱鶴齡和錢謙益(1582-1664)曾密切來往，卻因合作箋註杜詩而產生矛盾。隨著錢謙益在乾隆中葉後，因「貳臣」問題及著作語涉違礙等遭到清廷政治清算時，同樣身歷鼎革的朱鶴齡，其人品和學術卻都備受官方揄揚，其人其書甚至得隨四庫七閣本而鈔存天下。而他所撰〈書元裕之集後〉一文，亦為《四庫全書總目》所標舉。由於此文涉及人臣身歷二朝的臣節問題，圍繞此文產生的「表態」或「被表態」，或已不再僅是單純的文獻存佚問題，還涉及清代官方敏感的政治脈絡。《四庫全書》閣本文獻的差異，乃至於《總目》和「書前提要」的文獻出入，過去因文獻不易取得之故，未能被充分展現。然據今所見，《文津閣本四庫全書》中所收錄之朱鶴齡〈書元裕之集後〉一文，和《文淵閣本四庫全書》相較後，有明顯的差異。本文以〈書元裕之集後〉一文的文獻存佚問題為起點，藉由實際的文獻比對，以及對《文津閣四庫全書》和《文淵閣四庫全書》編纂歷程的考察，試著鈎稽出造成此一文獻差異現象的背後深層原因。〈書元裕之集後〉一文，乃至於整本《愚菴小集》在《四庫全書》兩閣本中的文獻存佚，不僅反映《四庫全書》的版本差異，也朗現潛藏在清代官方修書歷程裡，對某些牽動政治敏感神經的作者或著作，其間反覆刪汰、修改、商榷乃至於建構的權力運作痕跡。

Zhu he-ling(朱鶴齡1606-1683)is one of the most famous and important Confucian scholar in Qing dynasty. However, it was still uncommon that Zhu he-ling, a Ming-loyalist who was never employed by Qing court, was praised by Qing court through accepting his articles in the offical reserved catalogue(著錄書) in Sikuquanshu(四庫全書). Furthermore, the relationship between Zhu he-ling and QianQuanyi(錢謙益1582-1664)is meaningful. They came together because of similar academic interests, however they turned against each other due to different viewpoint in poetry. Qianlong(乾隆)regime in the Qing Dynasty emphasized their conflict for some political reason. This article attempts to explain the reason by verify different version of Zhu he-ling’s work ”yuanshiaoji(愚菴小集).”
