When the barcoding system was set up for serials, it was realised that the ISSN as a unique identifying number for the title could be used as part of the barcode to identify the serial. The ISSN is therefore the title identifier in the barcode. Magazine barcodes are represented in EAN format with a 2 digit add-on code.
For best results, search by ISBN. An ISBN is the 10 or 13 digit number, usually printed on the back of a book with a bar code, that serves as a unique identifier for the book. Searching by ISBN is the best way to search because it will get you the exact title and edition that you need.
