Perhaps one of the most prominent systems for identifying information sources is the unified international numbering that determines a unique identity for these sources. The International Standard Serial Number (ISSN) is the International Standard Serial Number (ISSN), which is used to determine a unique identity for sequential sources: Continuing Resources, which includes newspapers, magazines, and free papers that occur. Constantly, as well as websites that are constantly updated...etc.
The ISSN generally consists of eight digits, in which Arabic numerals from 0-9 are used. The last digit is allocated to the audit number, which is automatically generated and calculated on the basis of the factor 11 with weights from 2-8. The Roman numeral The review number is 10.
Since the ISSN is used in the same contexts as other symbols and codes such as the International Standard Book Number, the International Standard Number for Printed Music, and the Audio-Visual Works Code, this system should be preceded by capital letters (ISSN), and the number should appear in Two groups separated by a hyphen.
(ID: ISSN) is allocated by the national center entrusted with performing this task within the country, or by the competent regional center, where each successive source issued on a specific medium should obtain only one (ID: ISSN). In cases where there are fundamental changes to the title of a successive source, a new (ISSN) is assigned to it. As long as (ISSN) is assigned to a successive source, it should not be changed, replaced with another number, or reused on any other publication.
It has become common now to find information sources in general, and periodicals in particular, available on more than one information medium, especially after the spread of electronic publishing technology, which makes information sources available via information networks such as the Internet, or stored on CD-ROMs, in addition to their presence in print. Sometimes uploaded to microfilm or microfiche.
The appearance of successive sources, including periodicals, on multiple media (printed and/or downloaded on microfilm or microfiche, and/or on CD-ROM, online) has led to them obtaining different international standard numbers depending on the media on which they are published, which has caused There is a problem in linking the different forms of periodicals in the unified catalogs, with difficulty in the supply processes between publishers and libraries due to the treatment of each intermediary separately. Those interested in the matter of successive sources and their identification systems have tried to solve this problem, and so it was that (return the link: Linking ISSN) appeared. Which is known as (ISSN-L). This entailed the existence of a “metadata” that was specified for the successive source when (ISSN) was assigned to it, and another “metadata” after assigning the number to create a bibliographic record for the successive source in (the ISSN Register), Therefore, ISO issued the new edition of Standard No. 3297 to reflect these new changes.
