词典的书证不仅能够说明词义和用法,还可以证明义项的客观存在及源流。对一部“古今兼收,源流并重”的大型词典来说,丰富、准确、恰当的书证无疑是十分必要的。目前最大最权威的《汉语大词典》,孤证词条时或可见,极易造成释义、义项、书证等方面的错漏,影响词典质量。 The dictionary’s documentary card can not only explain the meaning and usage, but also prove the objective existence and origin of the meaning item. For a large-scale dictionary that combines “both ancient and modern, both origin and origin”, it is undoubtedly necessary that abundant, accurate and appropriate documentary evidence is available. At present, the largest and most authoritative “Chinese Dictionary”, when solitary evidence entries are visible, can easily lead to errors and omissions in terms of interpretation, meaning and documentary evidence, which affects the quality of the dictionary.
