钱大昕《十驾斋养新录》素为学林所重，近人至推为清人学术笔记第一，惜其书虽经再校，迄无注本，本论力图填此空缺，为此书作一笺注。笺注之义例，分为“明其源”、“纠其谬”、“补其缺”、“解其惑”、“申其正”、“探其理”、“衡其情”七种。明其源者，探寻钱说之论据也。纠其谬者，订正钱说之谬误也。补其缺者，补充钱说之不周也。解其惑者，解释钱说之疑惑也。申其正者，钱说为正解而他说非则申明其正确也。探其理者，钱说有知其然而不知其所以然则探其所以然也。衡其情者，诸说皆无确证则衡量其情理也。此为《〈十驾斋养新录〉笺注》弁言。

QIAN Da-xin’s Shijiazhai Yangxinlu has always been highly respected. It has been even regarded by modern scholars as the best among the Qing academic biji (a type of literature consisting mainly of short sketches). However, nobody has written commentaries on this remarkable work in spite of quite a number of collations. Trying to fill in the gap, this paper makes commentaries on this book. The commentaries consist in seven categories as follows: (1) tracing back to the provenance, that is, to find out the sources of QIAN’s views; (2) rectifying the faults, that is, to correct his errors wherever detected; (3) filling in the deficiencies, that is, to make complete his explanations which are insufficient; (4) solving the puzzles, that is, to expound his ideas which may cause doubt; (5) elaborating on the right, that is, to make clear that for which his views are correct while his opponents’ are not; (6) investigating the raison d’être, that is, to probe into the reason where QIAN only indicates the facts; (7) making a hypothesis, that is, to suggest the grounds wherever he arrives at a certain conclusion with no proof. This serves the preface.
