The SUNCAT software is about to be upgraded from Aleph 500 version 18 to Aleph 500 version 20. This will provide more functionality such as improved matching of records.
There will be no disruption to the service provided to users during the time the server is being upgraded as the service will run on another server, normally used to as a backup server.
We will not be updating SUNCAT with files from Contributing Libraries during this period but once the upgrading is complete every effort will then be made to load the accumulated backlog as quickly as possible.
Once we know when updating can recommence we will pass on that information.
