ISO 2108:2017确立了国际标准书号（ISBN）的规范，作为一种独特的国际标识系统，用于特定出版社出版或生产的、可供公众使用的单独专题出版物的每种产品形式或版本。它规定了ISBN的结构、分配和使用规则、与ISBN分配相关的元数据，以及ISBN系统的管理。 ISO 2108:2017适用于专题出版物（书籍），不适用于文本作品（内容）。专题出版物包括单独提供的章节，以及向公众提供的特定类型的相关产品，无论这些出版物是可供销售的还是免费的。 附录A中提供了适用和不适用产品的示例。 注:更详细的操作指南见本文件注册机构提供的最新版用户手册（见第7条）。

ISO 2108:2017 establishes the specifications for the International Standard Book Number (ISBN) as a unique international identification system for each product form or edition of a separately available monographic publication published or produced by a specific publisher that is available to the public. It specifies the construction of an ISBN, the rules for its assignment and use, the metadata to be associated with the ISBN allocation, and the administration of the ISBN system. ISO 2108:2017 is applicable to monographic publications (books), not to textual works (content). Monographic publications include individual sections or chapters where these are made separately available and certain types of related products that are available to the public irrespective of whether those publications are made available for sale or on a gratis basis. Examples of applicable and non-applicable products are provided in Annex A. NOTE More detailed, operational guidance is provided in the latest version of the Users' Manual available from the Registration Authority for this document (see Clause 7).
