Z39.50 is a national standard defining a protocol for computer-to-computer information retrieval. Z39.50 makes it possible for a user in one system to search and retrieve information from other computer systems (that have also implemented Z39.50) without knowing the search syntax that is used by those other systems. Z39.50 is an American National Standard that was originally approved by the National Information Standards Organization (NISO) in 1988.
Reference Database of Finnish Articles (ARTO), National Bibliography of Finland (FENNICA) and National Discography of Finland (VIOLA) use Aleph library management system. This document provides technical information for Z39.50 implementors that is necessary in order to access the Z39.50 servers for these databases. This document assumes a general familiarity with Z39.50.
The Union Catalogue of Finnish Libraries (Melinda) uses Aleph library management system. This document also provides the addresses for the LINDA Z39.50 Server.
We ask that you not use the Union Catalogues (ARTO and Melinda), FENNICA or VIOLA production databases with Z39.50 connection until you have successfully tested your client with a test database.

Z39.50 services supported
The server supports the following services:
All the Z39.50 servers also support the SRU protocol (v1.1) at the same address and port as the Z39.50 service. The SRU protocol is used over HTTP. Searches are made using the CQL language. The SRU service can return an "explain" response describing the supported search fields and record formats. Records are normally available in Dublin Core, MARCXML (i.e. MARC 21 in XML format, see the Finnish MARC 21 pages and The Library of Congress MARC 21 pages) and MODS formats.

Requirements and defaults: The Use attribute is REQUIRED.
For the other attributes, if an attribute type and value are not supplied by the client, the following defaults are applied at the National Library of Finland:
RELATION: -- Equal (value=3)
POSITION: -- Any (value=3)
STRUCTURE: -- Phrase (value=1)
TRUNCATION: -- Do not truncate (value=100)
COMPLETENESS: -- Incomplete subfield (value=1)
Keyword searches (i.e., Position attribute = "any-position-in-field"):
- Keyword search terms can appear anywhere in the field.
- If multiple words appear in the same search term, the search term will be processed as a phrase (ordered, adjacent word list).
- If the words appear in separate operands (ANDed together), they can appear in different fields in the same record.
- Personal name keywords: 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 order is significant. Last name should precede first name.
- Keyword indexing does not include phrases that cross subfield boundaries. If the search term contains a phrase that may cross subfield boundaries, use a left-anchored (right-truncated) search. (In other words, Position attribute = "first-in-field"; Truncation attribute = "right truncation".)
Phrase searches (i.e., multiple-word search terms):
- Phrase search terms 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.
- Personal name phrase searches: The order in which the names appear in the search term is significant. In other words, the surname should appear first (with or without a comma) in order to match against entry fields in the database indexes.
Number searches (ISBN, ISSN etc.):
- Use a hyphen in all ISSN search terms (e.g., 1234-5678).
- Use hyphens also in ISBN search terms.
- Searches are not supported against previous result sets.
- The question mark ("?") is supported as a truncation character.
- Keyword searches:
Records in keyword search result sets are in order by the Voyager control number (MARC field 001).
- Left-anchored searches:
Records in left-anchored search result sets are sorted by the field being searched (e.g., title, subject etc.).
