Help for libraries accessing our Voyager Z39.50 server

The Library uses the Voyager library management system supplied by Ex Libris.

The Voyager Z39.50 server conforms to Z39.50-1995 (version 3) of the standard. A subset of attributes from the bib-1 attribute set are supported, and codes from the bib-1 diagnostic set are utilised.

Connection details and hours of availability

The database is available 24 hours a day, except for about 10 minutes daily at 2.00am for routine maintenance.

  • Database: main collection
  • Domain name: catalogue.slv.vic.gov.au
  • Port: 7090
  • Database name: Voyager

Profiles supported

Z39.50-1995 (version 3) of the standard is supported. A subset of attributes from the bib-1 attribute set are supported, and codes from the bib-1 diagnostic set are utilised.

Target information

Z39.50 services supported

The Voyager server supports the following services:

  • initialisation
  • search
  • present

Initialisation service

The scan bit is on the Voyager init response, but scan is not supported.

The initialisation service is protocol version Z39.50-1995 (version 3). Options supported are search and present.

Preferred message size

Voyager will negotiate the client down to 16,000 bytes if the requested size exceeds 16,000 bytes and accept the client proposal if it is less than 16,000 bytes. The maximum record size is the same.

A user ID and password are not required.

Search service

Only 'default' is a supported result set name. Use 'voyager' as the database name. Both names are case sensitive.

'B' (brief) and 'F' (full) are supported element set names.

Only type-1 is a supported query and only bib-1 is a supported attribute set ID.

The result set ID ('default') cannot be used in the operand. Qualifying searches are not supported.

Supported operators are:

  • and
  • or
  • and-not

Record syntaxes are MARC 21 and OPAC.

Allowed searches

Email helpdesk@slv.vic.gov.au for more information about:

  • relation attributes supported
  • structure attributes supported
  • completeness attributes supported
  • required and default attributes
  • other attributes

Search term processing in Voyager system

Keywords

Keyword search terms (name, title, subject, note) can appear anywhere in the field.

If multiple words appear in the same search term, the search term will be processed as a phrase.

If the words appear in separate operands (ANDed together) they can appear in different fields in the same record.

A keyword search term can be the first, middle, or last name. If more than one name appears in the search term of a keyword search, the last name should precede the first name.

Keyword indexing does not include phrases that cross subfield boundaries. If the search term contains a phrase that may cross subfield boundaries (subject heading, LC call number, etc.), use a left-anchored (right-truncated) search. In other words, Position attribute = 'first-in-field'; Truncation attribute = 'right truncation'.

Phrases

Phrase search terms (name, title, subject, note) can appear anywhere in the field.

Phrase searches that include the first-in-field position attribute should begin with the first significant word in the field.

The last name should appear first (with or without comma) in order to match against entry fields in Voyager indexes.

Number searches

Use a hyphen in all ISSN search terms (e.g. 1234-5678).

Do not include hyphens in ISBN or LCCN search terms.

LCCN search terms should be in normalized format (i.e., include any prefix, spaces, or zero file). For example, LCCN 91-13 should be "91000013" in the search term.

Qualifying searches

Searches are not supported against previous result sets.

The questions mark is supported as a truncation character.

Sort order

Records in keyword search result sets are in order by the Voyager control number (MARC field 001).

Records in left-anchored search result sets are sorted by the field being searched (e.g., title, subject, call number, etc.).

Search term length limitations

Search terms, after mapping from intersite syntax to the internal Voyager search system, must not exceed 255 characters.

Limitations of Voyager server

There is a limit of 10,000 records that can be retrieved in a result set.

It is not possible to search the authority files.

When the Voyager server result set is a medium or a small set (based on the size of result set in relation to large-set, small-set, and medium-set number parameters in the Search Request) the following encoding problems can result:

  • When records are expected in the search response (e.g. a medium set or a small set), the presentStatus is a '0' (success) instead of a '5' (failure).
  • When a non-surrogate diagnostic record is returned instead of result set records in the search response, the value of numberOfRecordsReturned is a '0' instead of a '1'.
  • The non-surrogate diagnostic record never contains an addInfo, which is mandatory in the standard. If these problems are making interworking with the Voyager server difficult, it is suggested that the client small-set and medium-set number be set to zero and the large-set to one (making every set a large set) until these server problems have been corrected.

Guidance notes

Our catalogue includes records downloaded from Libraries Australia, a service for Australian libraries and their users which provides access to the national database of material held in Australian libraries.

Principles and guidelines on the use and transfer of records from Libraries Australia are available on its website.

Records may only be downloaded for private individual research purposes. Organisations requiring separate arrangements and should contact the Libraries Australia online or on 1800 026 155 (toll-free within Australia).
