This message will be of interest to cataloging and
Libraries wishing to upgrade may now install the new version of OCLC's
cataloging client, Connexion 2.0. A full list of features offered in
Connexion 2.0 is available at
Libraries are not required to upgrade to Connexion 2.0. OCLC will
not discontinue version 1.7 until a future release of Connexion is
Library staff making the transition from RLIN21 to Connexion should plan
to complete the process by the RLIN21 retirement date of August 31, 2007.
Connexion 2.0 accommodates RLG Union Catalog records and cataloging
practices by making RLG "cluster" records, now called
Institution Records (IR) available in WorldCat. Institution Records are
linked to OCLC Master Records and provide additional copies of the
WorldCat record, as cataloged by individual institutions, retaining each
libraries local data and notes. Connexion 2.0 makes Master Records and
Institution Records available to all users. RLIN21 users migrating to
Connexion 2.0 may prefer the cataloging in Institution Records; existing
Connexion users may continue to prefer cataloging in the OCLC Master
All users should be aware of changes to OCLC's MARC bibliographic format
coding and practice for Institution Records.
- OCLC's Institution Records contain an 079 field. Field 079 is
a new, non-repeatable field that appears in OCLC's Institution Records
only. Field 079 contains the OCLC number of the linked Master Record.
Institution Records are also assigned their own unique OCLC number. When
an Institution Record is exported to Aleph the OCLC number for the Master
Record will continue to be placed in the 035 field with first indicator
0. The Institution Record's OCLC number is moved to an 035 with a new
first indicator of 2. OCLC number in Institution Records will be added to
Aleph's existing OCLC number indexes and will be searchable by browsing
'Number: OCLC No.' index or by performing a command search using the KON
An OCLC tutorial on Institution Records is available at
- Institution Records cannot be used to overlay an Aleph record.
All Connexion 2.0 users may export Institution Records to Aleph,
but OCLC does not permit editing of Institution Records except by
members cataloging under that institution's holding symbol. Since
Institution Records contributed by other institutions cannot be edited,
they cannot be used to target an Aleph record. Catalogers may take
advantage of additional data in Institution Records by copying it into
the Master Record and using the modified Master Record to overlay a
record in Aleph.
an Aleph Bibliographic Record from OCLC and
to import a Bibliographic Record from OCLC have been updated on the
Aleph documentation web site to include these limitations.
Institution Records currently accessible in WorldCat are the
bibliographic "cluster" records migrated from the RLG Union
Catalog. During the next phase of the RLG transition, OCLC will begin
loading Institution Records for libraries that are sending records from
their local systems which includes all Harvard libraries. Institution
Records for Harvard will begin appearing in WorldCat as the OCLC
Reclamation project progresses. Harvard's Institution Records will be
added, updated and deleted automatically by batch processes. More
information on the RLG integration and WorldCat is available in
Tech Bulletin 254.
Z39.50 access to Institution Records will require configuration of
OCLCInstitutionRecords as a new target. Z39.50 searching of
OCLCInstitutionRecords is limited to OCLC number and holding library. OIS
is investigating Z39.50 access to Institution Records, and will notify
libraries when it is available.
