ISSN - Unique Number For Periodicals And Magazines
April 25th, 2007 — VyomaWell, it seems natural to me that I came across ISSN as I looked around to know more about ISBN and UPC.
There is nothing much, to state about ISSN, other than the fact that it is International Standard Serial Number.
ISSN is given to a periodical, or a magazine. It does not matter if it is print media or online media. It just has to be a periodical publication.
ISSN is a nine digit number, written as two four digit number separated by a hyphen, and the last digit being a checksum digit like with the other international numbers. Each periodical will be having a unique nine digit ISSN number that can be registered using the national based ISSN centers.
Note that ISSN is given to the entire periodical, and specific issue or volume cannot be specified using ISSN.
Considering that ISSN is for periodicals, be it print or online, are blogs (weblogs) entitled to get a ISSN. There seems to be quite a bit of argument going on for the case and also, there seems to be no consistency in the way, ISSN registrars of different countries act towards blogs. (See link).
