Changing sequences of categories include changing category sequence, category level, subordinate relationship and adding annotations. Generally speaking, original literatures won＇t be changed if the situation belongs to the problem of rough classification or detailed classification; original literatures will be changed if class numbers are very different, original categories are remote from new categories, original class numbers are occupied by new categories, in order to avoid confusing collections.%《中国图书馆分类法》（第5版）的修订主要表现为类目或局部类目体系的合并、分出和改序等变化。类目合并分为下位类合并到上位类、同位类或相关类目间的合并。类目分出分为上位类分出的内容增设下位类、同位类或相关类目分出的内容增设新类目。类目改序分为类序、类级、隶属关系的调整及增改注释等。凡属于粗分、细分之间的变化的类目，一般不用改编原分编文献；如果属于类号相差甚远、与文献原归属类目距离较远、被新类目占号的情况，应当改编文献，以免造成藏书混乱。
