图书分类的质量要求首先就是对图书资料的内容进行分析时要充分准确,进而做到辨类准确,分类准确。反之就会出现错误。例1,《吸烟与肺癌》归入“R163生活制度与卫生”,统编卡上的分类号就是如此。其根据就是把吸烟与健康作为本书的主要内容了.这是错误的理解。 Book classification of the quality requirements of the first is to analyze the contents of books and information to be fully accurate, and then do the correct type of classification, classification accuracy. On the contrary there will be mistakes. Example 1, “Smoking and lung cancer” are classified as “R163 System of Life and Health”, as is the classification number on the card. This is based on the idea that smoking and health are the main contents of this book.
