ISSN

An International Standard Serial Number (ISSN) is an eight-digit serial number used to uniquely identify a serial publication (periodical), such as a magazine.[1] The ISSN is especially helpful in distinguishing between serials with the same title. ISSNs are used in ordering, cataloging, interlibrary loans, and other practices in connection with serial literature.[2]

Not to be confused with ISBN.

The ISSN system was first drafted as an International Organization for Standardization (ISO) international standard in 1971 and published as ISO 3297 in 1975.[3] ISO subcommittee TC 46/SC 9 is responsible for maintaining the standard.


When a serial with the same content is published in more than one media type, a different ISSN is assigned to each media type. For example, many serials are published both in print and electronic media. The ISSN system refers to these types as print ISSN (p-ISSN) and electronic ISSN (e-ISSN).[4] Consequently, as defined in ISO 3297:2007, every serial in the ISSN system is also assigned a linking ISSN (ISSN-L), typically the same as the ISSN assigned to the serial in its first published medium, which links together all ISSNs assigned to the serial in every medium.[5]

The print version of a serial typically will include the ISSN code as part of the publication information.

Most serial websites contain ISSN code information.

Derivative lists of publications will often contain ISSN codes; these can be found through on-line searches with the ISSN code itself or serial title.

permits searching its catalog by ISSN, by entering "issn:" before the code in the query field. One can also go directly to an ISSN's record by appending it to "https://www.worldcat.org/ISSN/", e.g. n2:1021-9749 – Search Results. This does not query the ISSN Register itself, but rather shows whether any WorldCat library holds an item with the given ISSN.

WorldCat

ISSN is not unique when the concept is "a journal is a set of contents, generally copyrighted content": the same journal (same contents and same copyrights) may have two or more ISSN codes. A URN needs to point to "unique content" (a "unique journal" as a "set of contents" reference).
