What is ISBN?

The full term of ISBN is International Standard Book Number. This is a thirteen-digit number for the identification of a book. The Publishing industry’s activities can be controlled by this ISBN.

ISBN is for published hardcover and paperback books. ISBN code is different for different volumes. If a book has more than one edition, then all the editions will have different unique codes. The number is divided into five parts and connected with a hyphen.

Before 2007 the ISBN code used to be a ten-digit number. So if a book has a ten-digit ISBN, then it means that book was published before 2007.

ISBN may appear useless and insignificant to common people, but it is significant to the publishing industry, and it is important to get ISBN for every book.

The publisher of the book can be identified by the ISBN of a book. ISBN can not propose copyright, it is used to identify the book, and it is possible to find a specific book by its ISBN. In a paperback book, the ISBN can be seen on the bottom of the back cover. It can be written as a number or can be printed as a barcode. This makes the sales process easier.

A publisher has to get ISBN for every publication. It is mandatory. Otherwise, he/ she has to face legal issues.

What is ISSN?

In 1971 the ISSN system was formulated. ISSN is the abbreviation of International Standard Serial Number. ISSN is an international standards number to identify serial publications like newspaper, magazines, journals and other periodicals. Both online and offline publications can get ISSN code. It is an eight-digit number that comes after the uppercase ISSN. The eight digits are divided into two parts. Each part has four digits. The two parts are connected by a hyphen in between.

The code does not provide any information about the origin or contents of the publication, and it does not guarantee the quality of the material either. ISSN takes no responsibility for the content of the publication. ISSN does not ensure copyrights.

Publishers use it to identify their serial publications. Libraries also use it to identify and distinguish between identical serial titles. Academics use it for research purposes to cite the details of publications. ISSN helps to construct barcodes. ISSN’s International database is available online.

ISSN code can be seen on the cover page of the offline publication, and in the case of an online publication, one can see it on the home page. ISSN code remains the same for different issues of the same series.

This code is optional. The publishers are not legally bound to put ISSN code on a publication. It is not mandatory, so the publisher can avoid it if they want.
