The collective catalogue of the bibnet.lu library network is searchable via the Z39.50 protocol.
To use this service, it is necessary to have a Z39.50 client or a tool that supports this protocol (for example an Integrated Library System).
What is Z39.50?
Developed in the 80s, Z39.50 is a protocol used for searching and retrieving information form a database. It meets the ISO 23950 standard and is widely used in library environments. Thus, many Integrated Library Systems support this protocol.ISO 23950 – “Information and documentation — Information retrieval (Z39.50) — Application service definition and protocol specification”
How does Z39.50 work?
Z39.50 is a client-server protocol that is implemented on the application layer, which means that it works only over TCP/IP computer networks and does not make use of the HTTP protocol. The protocol is not intuitive to use, but supports search, retrieval, sort and browse functionalities.
