4 Identification of periodicals — International Standard Serial Number (ISSN)
Periodicals are identified worldwide via the assignment of an International Standard Serial Number and a key title. The ISSN is specified in ISO 3297 and it is an unambiguous numerical identifier that uniquely identifies a periodical title for searching, file matching, and other applications in libraries, information databases, the supply chain, rights management and other environments.
It is necessary to obtain a separate ISSN for each medium version of a periodical as defined by the ISSN Manual. When the same periodical or other continuing resource is produced in different media for which different ISSN and key titles are assigned, then the ISSN of all medium versions shall appear together on each version in a prominent location, each with additional distinguishing information. The Linking ISSN (ISSN-L) that collocates the medium versions shall also be displayed.
An ISSN shall consist of eight digits from the code points in the range U+0030 to U+0039 corresponding to Arabic numerals 0 to 9. The last digit or check digit (extreme right, low-order position) can also use the Latin capital letter X (code point U+0058). The check digit shall be calculated on a modulus 11 basis with weights 8 to 2, using X in lieu of 10 where 10 would occur as a check digit. The ISSN shall be constructed as two groups of four digits separated by a hyphen (U÷002DJ. The characters that comprise an ISSN are defined as code points from ISO/IEC 10646.
Since ISSNs are likely to be used in the same context as codes designed for other purposes, when an
ISSN is presented for human perception, it should, to avoid confusion, be preceded by the prefix ISSN (U+0047, U+0053, U+0053, U+004E) and a space (U+0020).
EXAMPLE ISSN 2274-1011 (Print), ISSN 2265-6405 (Online), ISSN-L 2265-6405 (Linking ISSN). Requirements for obtaining and using ISSN are found in Annex A.
5 Periodical title information
5.1 General provisions — Print and digital periodicals
The following provisions are applicable to all formats in which a periodical is published (e.g. print, digital/online, CD-ROM).
Provide the full title in a prominent, clear, and consistent manner everywhere it is possible to control the title presentation.
Use the same title for all formats of a periodical.
5.2 General provisions — Digital periodicals
5.2.1 The following provisions are particularly relevant and important to periodical content that has either been retrospectively digitized or where the title of a born-digital periodical has had a major change.
5.2.2 The title’s history and its relationship to former titles shall be clearly stated on the periodical homepage. It is not acceptable practice to put all digital content under the current title as that would render many existing citations useless. Librarians, library catalogues and the ISSN Network may be excellent sources of information about title histories. (See also 5.4.2).
5.2.3 Periodical information at the title level (including title and former titles each with their associated ISSN, subtitle, enumeration and date range, name of current publisher, place of publication, frequency, and other identifiers when applicable) should be supplied on the periodical homepage or other suitable location. Periodical information at the issue level (including title, volume number, issue number, nominal date of publication, name of current publisher, and ISSN) should also be specified on the title page of each article.ISO 8 pdf download.
