ISSN = Identification a simpler task in the print environment

??? Identification In the e-environmentIdentification e-environment E-commercetransactions ERMS Multiple Formats Library catalogs: single Vs. multiple records Open URL Linking

“Multiple ISSN Problem” One ISSN for the print publication One ISSN for the CD-ROM One ISSN for the online version Libraries, publishers, ISSN centers were using ISSN differently Search failures; OpenURL failures

Revision of the ISSN Standard (ISO 3297) Revision of the ISSN Standard (ISO 3297)

A separate ISSN for each version? A single ISSN to identify all versions?

Revised ISSN International Standard ISO 3297: 2007 published August 2007

Revised ISSN Standard (ISO 3297: 2007) Affirmed:  separate medium-specific ISSN Added:  Linking ISSN (ISSN-L)  represents all related medium-specific ISSN

ISSN designated by the ISSN Network to enable collocation or linking among the different versions of a continuing resource The Linking ISSN (ISSN-L)

Medium-specific Identification Used for specific “product” identification  Library ordering, claiming, check-in  Publisher pricing  Subscription agencies  EAN bar code  Copyright Clearance Center

EAN for a French Serial

Medium-Neutral Identification/Collocation OpenURL resolution regardless of multiple ISSN for manifestations Grouping of all versions in ERMS OPAC searching to retrieve all manifestations All situations where identification without regard to medium is desired

How Does ISSN-L Get Assigned? ISSN-L is added to 022 $l on entry into the ISSN Register, Paris (programmatically) ISSN of first medium version entered into the ISSN Register = ISSN-L Applies to all resources: whether published in one medium or more, current or ceased In 2008, all records then in ISSN Register were allocated ISSN-L (lowest ISSN from the cluster linked via 776 field)

Can ISSN-L Be Predicted? Depends on which ISSN record is processed first in Paris Different medium versions can be published in different countries No

ISSN-L is a separate data element. Store ISSN-L separately from ISSN in knowledge bases and systems. Storing ISSN-L in Systems

Embedding ISSN-L DOI doi: /issnl OpenURL As illustrated in ISO 3297

Major Title Changes If titles of all versions change at once (most common situation):  A new group of ISSN is assigned  The first-assigned is the Linking ISSN If all do not change at once, any new titles “inherit” the ISSN-L of the unchanged titles Now handled programmatically in Paris

No separate metadata record for ISSN-L

Examples of ISSN-L Use

All relevant ISSN including Linking ISSN

Print ISSN and Linking ISSN both Included in MEDLINE Citation

PEPRS Project U.K. E-journals preservation registry project partnering with ISSN Network ISSN-L is the matching key: supports aggregation of data from various sources ISSN-L ensures matches regardless of data which version’s ISSN (“p” or “e”) used

Linking ISSN

Your Input: Currently, ISSN-L automatically assigned in Paris, a week+ after U.S. assignment Do publishers want to receive ISSN + ISSN-L together? Do publishers intend to print ISSN-L? Is waiting an extra week ok? Alternatively, the U.S. can explore designating the ISSN-L in select cases
