清河郡本《乐纬》是一部来历不明之书。该书存在大量独有佚文,加之人们对其文献学性质认识模糊,故对其文献价值称赞有加。然经深入辨析后可以知道:该书是辑佚书而非原本,其独有佚文多系伪造或误辑。因此,以往人们对该书的评价极为不当。该书不惟文献价值不值得称道,反而是我们需要慎重处之的对象,以免被其“独有佚文”所误导。 Qinghe County, “Le Wei” is a book of unknown origin. There are a large number of unique Lost Essays in the book, combined with the vague understanding of the nature of its bibliography, its appreciation of the value of its literature adds. However, after further analysis, we can know: The book is not the original edition of the book, not the original, and its unique collection of fictitious or false edit. Therefore, in the past people’s evaluation of the book is extremely inappropriate. The book is not worthy of commendable value of the literature, but rather we need to be careful of the object, so as not to be “misleading”.
