To those of you who have been testing the Z39.50 interface on 142.28.224.14, you should know that some other Koha features on that machine are badly broken at the moment. I'm working on integrating full MARC record support on that machine, so things like editing records are in a sad state. In particular, I know that Modifying a biblio record will result in an internal server error, although it will successfully modify the biblio record and the underlying MARC record before returning the error. :) I've changed the z39.50 querying daemon so that it will fork up to 20 separate processes for doing queries. This speeds up the results considerably. I've also set up a new database table so that additional Z39.50 servers can be added for different Koha installations quite easily. Thanks to everyone who's been testing this and pointing out my obvious mistakes. :) Steve.
