• What BibLinking is• History• How BibLinking works

– in cataloging – in WebVoyàge – configurations

• Conclusions

• According to ”Voyager 2001.1 Bibliographic Record Linking and MARC Derivation of Records User’s Guide” April 2002, BibLinking enables:– Defining relationships between bibliographic

records using profiles made in SysAdmin module

– Displaying relationships in WebVoyage (and in Cataloging module)

– Maintaining relationships with templates (and with derivation fields) in Cataloging module

What Bibliographic Linking is

• Relationships can be:– vertical, eg. between ”parent” (=host)

and ”children” (=component parts) – sibling, eg. between parts of a

multivolume set– chronological, eg. predecessors and

successors– horizontal, eg. different versions of the

same bibliographic item

What BibLinking is (cont.)

Vertical relationship: Music host record with its contents

Contents

A record of one track with information of a sound recording as a host

Publication

What BibLinking is (cont.)

• Links are made to both directions– from host to component part and vice versa

• One record can have multiple relationships– a record can simultaneously have different kind

of relationships– a component part can have its own component

parts– a component part can have multiple hosts

History of BibLinking in Finland

• A related records feature was used in four DBs in the former library system (two music, two article databases)

• Since June 1999 we have worked with EISI with the BibLinking product– 2001 the first Voyager DB with BibLinking

(Arsca) opened– Helsinki University Databases VIOLA and

ARTO January 2002

History (cont.)

Essential features of BibLinking for us:- the main basis of the links between hosts and

component parts should be the Bib/001 of the host and the 773|w of the component part record

- the system must be able to handle hundreds, even thousands of component parts

Music databases with BibLinking

VIOLA http://viola.linneanet.fi

the Finnish national discography and union catalogue of music

Arsca http://arsca.linneanet.fi (free access)

the database of 8 art libraries, 4 of them music libraries

3 databases of polytechnic libraries (2003-)

BibLinking in Cat module

• Related records are maintained in the Cataloging module• Cataloging, copying, editing and deleting of the related

records are similar to the cataloging of ”ordinary” bibliographic records

• Templates with derivation fields can be used• Related records can be searched and displayed in

Cataloging module (and in WebVoyàge)• Related records can be relinked easily

BibLinking Configurations in general

• In SysAdmin module (System -> Search config. -> BibLinking): the configurations for– links between related records for cataloging and

WebVoyàge – displays of related records in cataloging and partly in

WebVoyàge

• In displayN.cfg: the configurations for– the links to be displayed in general in WebVoyàge

• In opac.ini: the configurations for– separate displays in WebVoyàge

SysAdmin -> System -> Search configuration ->

BibLinking configurations for WebVoyàge

• In displayN.cfg ( a new code): Publication:3500 HOST (the same profile code name as in SysAdmin BibLinking)Contents:3500 COMP (the same profile code name as in

SysAdmin BibLinking)

Conclusions

+- Navigation between hosts and contents is practical. The message ”Click here to get the original record” may be confusing

+- Catalogers must be very careful when copying records, eg. not to create uncorrect links

+- Catalogers have to understand the basis of the linking for not to create incorrect relationships in the DB

Conclusions (cont.)

- Links are not retained when copying or loading host with its component parts from DB to DB (if links can not be based on standard numbers) and copying is possible only one record at a time

- Templates (derivation fields) complicated to modify

- Fixed fields cannot be derived from the host record

Conclusions (cont.)

+ BibLinking is flexible (eg. templates with derivation fields for several purposes, relink)

+ Links in WebVoyàge working fine in music DBs

-> BibLinking is an essential tool in music cataloguing
