AS ISO 3297:2018 pdf free.Information and documentation – International standard serial number (ISSN)
An ISSN shall consist of eight digits, using Arabic numerals 0 to 9, except for the last digit (extreme right, low-order position) which can also use the upper case letter X. The last digit shall be the check digit. 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. See Annex A for further details.
Since ISSN are likely to be used in the same context as codes designed for other purposes, such as the International Standard Book Number [ISBN] or local control numbers, the written or printed presentation of ISSN shall clearly distinguish ISSN from other numbering systems. Therefore, an ISSN shall be preceded by the prefix ISSN and a space, and shall appear as two groups of four digits separated by a hyphen.
The key title is derived from information appearing at the time of registration on the title page of resources having a title page or title page equivalent, or from the most complete information formally presented on resources lacking a title page. The title of the resource becomes the key title if this title is unique in the ISSN Register at the time of registration. If this title is not unique, the key title is the title of the resource, to which a qualifying term is added (such as name of issuing body, place and/or date of publication, edition statement or medium statement), in order to make the resulting key title unique.
When a single continuing resource bears more than one ISSN in relation to different continuing resource titles, for example the titles of a main series and its subseries, each ISSN shall appear on the continuing resource and each shall be distinguished by either adding the full or abbreviated title in parentheses after the relevant number, or by printing each ISSN as close as possible to the relevant title.AS ISO 3297 pdf free download.
