z3950server[.xml|json]?active=[nil|true|false]&source_type=[library|uls|archive]

GET

Lists Z3950 servers for active member institutions, for the Unified List of Serials, and (potentially) for archives - there are currently no archives listed. The optional 'active' parameter refers to whether Search25 can currently access the Z39.50 server.

This command is of little use to any users apart from Search25, as it returns no details for the servers themselves.

Example: /z3950?active=false&source_type=library lists institutional servers which cannot currently be accessed by Search25
