全国统一书次号编码系统研究

A Further Study of the Coding System for the National Standard Serial Number of Books(NSSNB)

数字化检索系统不仅需要书次号 ,更需要规范统一、科学性强的书次号。出版号编码 ,利用了 ISBN中的出版者代号 +出版物的流水号 ,经过重组 ,形成一组恒定的八位数数据。该编码系统具有规范统一、科学性强的特点 ,其中的任何一个编码都是唯一的 ,无论如何使用都不会发生重号现象 。

For the digital retrieval system,not only is the serial number of books(SNB)needed,but also required more standard and more scientific SNB.The coding system for CIP(China index of publishing),which is made up of invariable eight digitals,has been restructured through processing the data out of CIP in ISBN and SNB.The system is characterized by more standard and more scientific aspects.For any group of the coding system,the codes are unique and whenever they are used,the same codes are certainly not repeated.So the NSSNB coding system can be regarded as the best database in building the standard digital retrieval system.
