The dean wasn’t interested, but Silver was, and with Woodland began to explore the problem. Silver had overheard the president of a chain of supermarkets asking the dean of Drexel’s engineering department to research a device that would reduce cashier errors at check-out – errors that were eating into the supermarkets’ narrow profit margins. The bar code was invented by Bob Silver and Norman Joseph Woodland, two graduate students at the Drexel Institute of Technology in Philadelphia in the late 1940s. Groceries in supermarkets, books in libraries, luggage in airports, rental cars, nuclear waste: bar codes keep track of everything. It’s a bridge between objects and electronics that makes the incredible complexity of the modern world possible. But they are the closest thing humanity has to a universal language – a language we share with machines. These strips of parallel vertical lines of varying width are ubiquitous enough to be near-invisible. a manual) it might be eligible for an ISBN number and corresponding barcode.You’re never far from a bar code. Items that aren’t eligible for an ISSN will need a standard “EAN-13 Barcode Package” instead (you can purchase this from our shop page). The following items are not considered a “serial” therefore they shouldn’t have an ISSN number: instruction manuals one-off ‘book-a-zines’ posters magazine or newspaper special editions serials not intended for public circulation diaries calendars mail-order catalogues and fill-in crossword or puzzle books. You need an ISSN number (and corresponding barcode) for anything that is considered a “serial” – e.g. magazines, newspapers, journals, yearbooks, directories and monographs in series.

If you have printed music you’ll need to get an International Standard Music Number (ISMN), and then get that turned into barcode images.

Other countries tend more towards the 13 digit formats (options 1 and 2). In the UK the 13+2 format (option 3) is the most common. The supplement changes for each issue and can be done on a monthly (01-12) or weekly (01-52) basis (or any other way you wish). The final format involves converting the ISSN number in exactly the same way as option one, however, in this case, an additional 2-digit supplement code is added to the end creating a 15 digit (EAN-13+2) number. In this case, a separate barcode image would be created for each issue of the magazine.ģ. Again the 8 digit ISSN number is converted to a 13 digit number, however, this time the ’00’ added on the end is changed various times to create a different EAN-13 image each time. In this case, the same number would be printed on each issue of the magazine.Ģ. The number is then created as an image using EAN-13 Symbology which can easily be read by all barcode scanners and is essentially the same as other products with EAN-13 barcodes on them that go into stores. The 8 digit ISSN number is converted to a 13 digit number (EAN-13) by adding a 977 to the beginning, taking away the check-digit, adding two numbers (00) to the end and recalculating the check digit.
