申请ISSN
（一）What is an ISSN?
An ISSN is an 8-digit code used to identify newspapers, journals, magazines and periodicals of all kinds and on all media–print and electronic.
ISSN是什么？
ISSN是由8个数字组成的编码，旨在识别各种报纸、专业杂志、画报、期刊，无论其性质或载体版本（纸质版及电子版）。
英文名称：International Standard Serial Number
中文名称：国际连续出版物号
英文缩写：ISSN
中文简称：国际刊号
（二）Which publications are concerned by an ISSN?
An ISSN (International Standard Serial Number) identifies all continuing resources, irrespective of their medium (print or electronic):
newspapers,
annual publications (reports, directories, lists, etc.),
journals,
magazines,
collections,
websites,
databases,
blogs,etc.
In many countries, an ISSN is mandatory for all publications subject to the legal deposit.
ISSN号涉及哪些出版物？
ISSN（国际标准期刊号）对所有连续资源予以识别，无论其采用印刷或电子载体版本：
报纸
年度出版物（报告、年鉴、汇编等）
专业杂志
画报
丛书
网站
数据库
博客等
在很多国家，所有送缴收藏的出版物都必须拥有ISSN号。
（三）What form does an ISSN take?
The ISSN takes the form of the acronym ISSN followed by two groups of four digits, separated by a hyphen. The eighth digit is a check digit calculated according to a modulus 11 algorithm on the basis of the 7 preceding digits; this eighth control digit may be an “X” if the result of the computing is equal to “10”, in order to avoid any ambiguity.
e. g.:
ISSN 0317-8471
ISSN 1050-124X
ISSN号的格式？
ISSN号的格式如下，ISSN缩写后两组各四个数字，中间由连字符分开。第八个数字是根据前七个数字按模数 11算法计算得出的检验码。若计算结果为10，第八个数字可为“X”，以避免出现模糊不清的情况。
例如：
ISSN 0317-8471
ISSN 1050-124X
（四）What is its role?
The ISSN role is to identify a publication.
It is a digital code without any intrinsic meaning:
it does not include any information about the origin or contents of the publication,
it does not guarantee the quality or validity of the contents.
The ISSN is associated with the title of the publication. If the publication is modified significantly, a new ISSN must be assigned.
ISSN号的作用？
ISSN号的作用是对出版物予以识别。
ISSN号作为数字编号并无任何内在含义：
不含任何涉及出版物来源或内容的信息
不担保出版物内容的质量或真实性
ISSN号与出版物题名相关，若题名发生大幅度变化，将应分配新的ISSN号。
（五）Where is it displayed?
For a print publication, the ISSN should be shown:
preferably, in the upper right corner of the cover,
failing that, on the pages where editorial information is shown (publisher, frequency, colophon, etc.).
For a publication in electronic media, the ISSN should be shown:
on the homepage or on the main menu, if it is an online publication,
on any part visible to the naked eye (microfiche header, CD-Rom or DVD label, box, case, etc.), if the publication is on a physical medium.
If a publication is identified by ISSN and ISBN, both of these identifiers should be mentioned.
ISSN号显示在哪里？
对于印刷出版物而言，ISSN号应显示于：
最好在封面右上角
否则在承载编辑出版信息（出版方、周期性、版本信息等）的页面
对于采用电子载体版本的出版物而言，ISSN号应显示于：
在线出版物的首页或主菜单
采用物理载体的出版物的任何裸眼可读取部分（缩微标签笺头、CD光盘或DVD标签、包装盒套等）
若相关出版物同时拥有ISSN号和ISBN号，两个识别号都应得以显示。
