2. OverviewOverview
 More data (content) requires more metadata
 Metadata needs standardization and quality control in
order to function well
 ISSN and other identifiers can help connect data and
metadata
 ISSN—properly used– can help keep metadata
synchronized so it can work effectively
 ISSN can be used to clean dirty metadata
 Access to centralized ISSN data can help keep it
clean
 Ongoing exchanges between libraries and other
actors can help keep data and metadata
synchronized

 Which database to search?
 Where is it in the A – Z list?
 Listed database does not have full text
 Multiple hits: which has the issue?
 The library does not have the article in
online form, does it have it in print?

10. ISSN MythsISSN Myths
 ISSN can be assigned to current serials only
 Publishers self-assign ISSN
 There is a charge to get an ISSN
 ISSN is only a U.S. standard (NISO Z39.9)
 ISSN have been assigned for the past 15 years
 The ISSN system is controlled by the Library of
Congress
 OCLC records are the best source for ISSN
 Ulrich’s records are the best source for ISSN

26. ““Multiple ISSN ProblemMultiple ISSN Problem””
 ISSN policy: separate ISSN for e-version
 Some publishers were using single ISSN
 Some OPACs have separate records;
others have single records
 Failures in OpenURL linking, record
merging, de-duping, etc.

30. The Revised StandardThe Revised Standard
 Affirms policy of separate medium-
specific ISSN
 Adds new collocating mechanism:
linking ISSN (ISSN-L)
 Catalyst for ISSN User Group
 Covers all continuing resources,
integrating as well as serials

31. Medium-specific IdentificationMedium-specific Identification
 ISSN remains at this level
 Per ISSN Manual: separate ISSN for
print, online, CD-ROM, etc. versions
 Same level prescribed by AACR2
 Used for specific “product” identification
– library ordering, claiming, check-in
– subscription agencies, EAN, CCC

Identification/collocationIdentification/collocation
 OpenURL resolution regardless of multiple
ISSN for manifestations
 Collocation in ERMS
 OPAC searching to retrieve all manifestations
 E-articles, bib records, or ERMS entries where
there is no full online version of the serial
 All situations where identification without
regard to medium is desired

34. ISSN-LISSN-L
 First-assigned medium-specific ISSN

36. Retrospective ISSN-L DesignationRetrospective ISSN-L Designation
 Entire ISSN register populated with ISSN-L
 All resources will have an ISSN-L--whether
published in one medium or more
 Ceased and current resources to have ISSN-L
 Retrospective designation uses lowest ISSN
from the cluster linked via 776 field
 Future (ongoing) designation will use the
first-assigned ISSN*
 ISSN-L cannot be predicted; some situations
will be complex
*May not always be the lowest in numerical order
because of the way ISSN are allocated to ISSN centers

 Exchange of “clean” metadata:
publisher gets authoritative ISSN; ISSN
record based on metadata from source
 Creation of baseline OPAC records, for
enhancement with controlled headings
 Closer ties between publishers and
libraries
 Potential metadata exchange partners:
A&I services, OpenURL knowledge
bases, vendors, PAMS
