For example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is ten digits long if assigned before 2007, and thirteen digits long if assigned on or after 1 January 2007. The method of assigning an ISBN is nation-specific and varies between countries, often depending on how large the publishing industry is within a country.\n\u003e  \n\u003e The initial ISBN identification format was devised in 1967, based upon the 9-digit Standard Book Numbering (SBN) created in 1966. The 10-digit ISBN format was developed by the International Organization for Standardization (ISO) and was published in 1970 as international standard ISO 2108 (the 9-digit SBN code can be converted to a 10-digit ISBN by prefixing it with a zero digit \"0\").\n\n## Installation\n\nThe preferred method of installation is via [Packagist][] and [Composer][]. Run the following command to install the package and add it as a requirement to your project's `composer.json`:\n\n```bash\ncomposer require pfazzi/isbn\n```\n\n[packagist]: https://packagist.org/packages/ramsey/uuid\n[composer]: http://getcomposer.org/","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpfazzi%2Fisbn","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpfazzi%2Fisbn","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpfazzi%2Fisbn/lists"}
