④ Book serial number: the fourth part of China Standard Book Number. According to the order of publication, it is managed and compiled by the publishing house. For example: ISBN 978-7-5366-8679-3, in which the book serial number "8679" indicates that this is the 8679th book of Chongqing Publishing Group published by the publishing house "7-5366".
Pay special attention to the use of publishing house numbers: from the length of each group number in the above figure, we can find a rule that the length of book number depends on the length of group area code and publishing house number. According to the rules of this game, the smaller the number of publishers, the more books publishers can produce, and the larger the number of publishers, the less books publishers can produce. However, the distribution of "publisher number" by the publishing authorities in China when implementing ISBN standards is based on the concepts of so-called big clubs and small clubs in the planned economy era. Since the reform and opening up 30 years ago, the development of publishing houses in China's publishing industry has been extremely uneven. An objective reality is that the publishing varieties of some publishing houses have far exceeded the number of publications stipulated in ISBN, so there are many publishing houses in China's book industry at present. For example, Hainan Publishing House has four publishing numbers: ISBN 978-7-5443, ISBN 978-7-80590, ISBN 978-7-806 17 and ISBN 978-7-80645.
