《今乐考证》虽然是一种戏曲目录,但它具有不可取代的戏曲史价值。表现在它著录了戏曲史上大量的近于完备的剧目;且在著录中纠谬正误,构筑了戏曲史的基本框架,这在戏曲研究史上是前无古人的。 Although it is a kind of opera catalog, “Jinle Textual Research” has irreplaceable historical value of opera. This is reflected in the fact that it recorded a large number of nearly complete repertoire in the history of the opera. In addition, it erroneously corrected mistakes in the bibliography and established the basic framework of the history of opera, which is unprecedented in the history of Chinese opera studies.
