Z39.50 Configuration for the Rutgers University Library Catalog


About Z39.50

Z39.50 is an international communications standard that specifies a client/server based protocol for searching and retrieving information from remote databases. The advantage of this standard is that computer systems can be separately developed with custom search syntaxes but can talk to each other as long as they comply with the protocol.

The database engine that underlies the library catalog comes with a Z39.50 server. Patrons can use standalone Z39.50 client software or bibliographic management software containing Z39.50 clients, like RefWorks, EndNote, or ProCite, to connect to the library catalog and search and retrieve citations relating to bibliographic records. This web page describes the elements that are needed to make a connection to the Z39.50 server and to perform successful searches of the library catalog.

Encoding Definitions

The Z39.50 standards makes use of attributes to "code" a client's query so that the receiving server can process the query correctly. There are provisions for six encoding definitions in the Z39.50 standard.

USE or INDEX
- Specifies which data field(s) the query should be processed to
RELATION
- Controls the order of numerical expression
POSITION
- Specifies the location of term(s) within the fields for matching query
STRUCTURE
- Specifies the structure of data in the query
TRUNCATION
- Specifies type of truncation processing for query
COMPLETENESS
- Specifies query processing by subfield

Attribute Value Notes

Relation Attributes 1=less than 2=less than or equal 3=equal
4=greater than or equal 5=greater than  
Position Attributes 1=first in field 3=any position in field  
Structure Attributes 1=phrase 2=word** 4=year
6=word list 101=normalized name  
Truncation Attributes 1=right truncation 100=do not truncate  
Completeness Attributes 1=incomplete subfield 3=complete field  

**As per the requirements of the Bath Profile, the server will not process a multi-term structure "word" search term. Multi-word keyword searches must be encoded as single "word" terms combined with the boolean "AND" operator.
