ISBN and ISSN are unique identification codes established for information control, exchange, and retrieval of various media publications (newspapers, journals, magazines, and books, etc.). Searching ISBN and ISSN can quickly and effectively identify the publication location, publisher, title, and version of a publication.

ISBN (International Standard Book Number) is the international standard book number for periodic publications

ISSN (International Standard Serial Number) is the international standard serial number for regular publications

With the above two numbers, it indicates that the publication has been registered with ISBN or ISSN international institutions and has reached international standards. The background information of the publication can be queried at any time through the numbers, enhancing readers' confidence in the publishing house.
