《中图法》上位类复分或仿分不需要加“0”情况全解

Full Solution to the Upper Class Subdivision Without Adding “0 ”When Using the Chinese Library Classification(Fifth Edition)

《中图法》上位类目进行复分或仿分时一般需要在复分或仿分号之前加“0”,但是有些情况不需要加“0”。文章通过对《中图法》第五版中可以进行复分或仿分的上位类逐一进行梳理分析,归纳出上位类复分或仿分不需要加“0”的情况:上位类依N/X类的专类复分表分;上位类仿类名为“一般性问题”的类目分;上位类复分或仿分时需要加辅助符号;上位类之下已为复分或仿分类目预留类号;下位类采用借上级类号法。对于比较容易出错的情况,文章还采用列表形式详尽列举出复分或仿分不需要加“0”的上位类,以方便标引人员掌握。

When the upper category of CLC is subdivided and imitated,it is generally necessary to add“0”before the compound division and imitation semicolon,but in some cases it is not necessary to add“0”.Through the analysis of the upper class which can be subdivided and imitated in the fifth edition of Chinese Library Classification,this paper concludes that there are five situations in which the upper class does not need to be added with“0”:the upper class is divided according to the special category subdivision table of N/X class;the upper class is divided by means of imitation of the category with the name of“general problem”;the upper class is divided by means of imitation of the upper class needs to be added with auxiliary symbols when the upper class is subdivided and imitated;the class numbers have been reserved under the upper class for the taxonomic subdivision;the lower class adopts the method of borrowing the superior class number.For the cases that are easy to make mistakes,the paper also lists the upper classes which do not need to add“0”in the form of list,so as to facilitate the indexing personnel to master them.
