The ISSN: a reminderThe ISSN: a reminder–1,500,000 ISSN assigned so far

–Available in the « ISSN Register »

–An international network of 86 National Centres

–Coordinated by the ISSN International Centre (Paris)


The ISSN-L : its originThe ISSN-L : its origin–The ISSN-L concept was the fruit

of the revision of the ISSN ISO standard, revised in 2007

–Two families of users with contradicting but strongly expressed needs…


The ISSN/ISSN-L philosophyThe ISSN/ISSN-L philosophyTwo diverging needs :

• Product identification (ISSN)• distinct ISSN for the distinct editions of a given continuing

resource• Separate ISSN for the various media versions of a

resource

• Contents identification (ISSN-L)• group, or collocate, the various media versions• One and only one identifier (Unique ISSN-L for the

various media versions)


What is the ISSN-L?What is the ISSN-L?• An existing ISSN, designated to function

as ISSN-L• Common to the various media versions of

a resource– Dance research (Print) = ISSN 0264-2875

ISSN-L 0264-2875– Dance research (Online) = ISSN 1750-0095

ISSN-L 0264-2875


Designation of ISSN-LDesignation of ISSN-L

• From among the different ISSN assigned to the different media versions of a continuing resource

• Automatically in the ISSN Register

• Or by the ISSN Centres


Retrospective designationRetrospective designation• Entire “ISSN Register” has been populated with ISSN-L

• All resources have an ISSN-L whether published in one medium or more

• Both ceased and current resources have ISSN-L


How are ISSN-L designated?How are ISSN-L designated?

• The first ISSN assigned in the ISSN Register to any medium version of a continuing resource

• On the basis of linking fields (776 in MARC 21 or 452 in UNIMARC)

• Designated by default to function as the ISSN-L• Applies to all other medium versions in the Register

at the time of designation or added in the future


Is there a way to determine the ISSN-L Is there a way to determine the ISSN-L from the medium specific ISSN? from the medium specific ISSN?

• Short answer : No

• ISSN have no inherent meaning

• Which medium version record will enter the ISSN Register first and become the linking ISSN cannot be predicted

• Different medium versions can be published in different countries


Examples of ISSN-LExamples of ISSN-L• Continuing resource in only one medium form

– Algorithms for molecular biology = ISSN 1748-7188

» ISSN-L 1748-7188• Continuing resources in two medium forms

– 40 ans! (Imprimé) = ISSN 1913-5149– 40 ans! (En ligne) = ISSN 1913-5157

» ISSN-L 1913-5149

• Continuing resources in three medium forms– Plant varieties journal (Ottawa, Print) = ISSN 1188-1534– Plant varieties journal (Ottawa, Online) = ISSN 1911-1479– Plant varieties journal (Ottawa, CD-ROM) = ISSN 1911-1460

» ISSN-L 1188-1534


Recording of ISSN-LRecording of ISSN-L• A new data element in UNIMARC

Field 011 subfield f = ISSN-LMade-up examples:

• 011 $a1913-5149 $f1913-5149• 011 $a1913-5157 $f1913-5149

• A new data element in MARC 21Field 022 subfield l = ISSN-LMade-up examples:

• 022 $a0264-2875 $l0264-2875• 022 $a1750-0095 $l0264-2875


Title changesTitle changes• If all titles of the medium versions

change at the same time, new medium specific ISSN are assigned and therefore a new ISSN-L is designated

• In the other cases the ISSN-L remains unchanged

Possible uses of ISSN-LPossible uses of ISSN-L• OpenURL resolution regardless of multiple

ISSN for different manifestations

• Collocation in ERMS

• OPAC searching, so as to retrieve all manifestations

• All situations where identification without regard to medium is desired


17

ISSN-L used in Open URLISSN-L used in Open URL

• Typically an Open URL resolver attempts through its knowledge base to display potential locations

• If the submitted ISSN is « print » and the stored ISSN is « online », resolution failure is possible

• ISSN/ISSN-L matching tables can help to solve the issue within the knowledge base…

ISSN-L implementationISSN-L implementation

• OCLC (Worldcat) is adding ISSN-L data to its records

• The PEPRS project (Piloting an E-journals Preservation Project) is internally using the ISSN-L as a matching key
