What is the difference between bar code and ISBN?

Answer 1

• The ISSN identifies the title of a serial and stays the same from issue to issue unless the title changes, at which point a new ISSN needs to be assigned.
• The ISBN (International Standard Book Number) represents a single volume such as a novel, a monograph, a specific title within a monographic series or a specific issue of an annual or yearbook.

Answer 2

A barcode is a visual representation of data that can be scanned by a machine for identification or tracking purposes, whereas an ISBN (International Standard Book Number) is a unique numeric identifier assigned to each edition and variation of a book. In essence, a barcode is a machine-readable representation of data, while an ISBN is a specific identifier for books.

Answer 3

ISBN is a book numbering system to uniquely identify commercially-available books.

Bar codes are an identification system for pretty much any item, not just books.
