元人廼贤所著《河朔访古记》,今存多个版本,皆源自四库馆臣从《永乐大典》中辑出的残本,其中文津阁《四库全书》本和文渊阁《四库全书》本,是比较重要的两个版本。两种四库本由于抄手和所据底稿的差异,存在大量不同之处,可分为字体不同、文字不同等几个方面。通过对两个版本逐字逐句比勘,可知文津阁本校上时间较早,是较原始的本子。文渊阁本校上时间较晚,是修改后的本子。两种四库本各有优劣,可以互补,不可偏废。

Several editions of a Visit for Ancient Relics of Heshuo written by Naixian of the Yuan dynasty have been preserved, all of which originated from the remnants of the Yongle Encyclopedia collected by the editors of Siku Quanshu. The two most important editions are from the Siku Quanshu of Wenjin Chamber and the Siku Quanshu of Wenyuan Chamber. There are many differences between the two editions, which can be divided into several aspects, such as different typefaces, different characters, etc. Through a word-by-word comparison of the two editions, it can be seen that the edition of Wenjin Chamber was a more primitive version of the book, compared with that of Wenyuan Chamber. The two editions have their own advantages and disadvantages. They can complement each other, and neither can be neglected.
