书次号是各馆区分同类异种图书的次序号,只有特殊性没有普遍性,因而无需统一每种书的书次号;书次号方案与书次号的选取是分离的,即统一书次号方案是一回事,书次号的编码又是另一回事,统一书次号应理解为统一采用某种书次号作为排列同类书的依据,而不应理解为统一每种书的书次号。 Book number is the classification of different museums of the same book number, only the particularity is not universal, so there is no need to unify the book number of each book; book number program and book number selection is separated, that unified book number program is a It is another matter that the number of the book and the number of the book is another. The unified book number should be understood as a uniform basis for using a book number as the basis for arranging similar books, and should not be understood as unifying the book titles of each book.
