Books or CDROM for registrations

I assume you want some ‘spotting’ database. I’m currently using Aerodata and am happy with the product and service. http://www.aerodata.org/

I wonder where i can get either a book or CDROM that has the planes regi’s on ( if there is a CDROM verson can it be updated online) Currently i live in NZ

Hi Mudhouse, although not really what you wanted, you could try the wiki link at:

http://en.wikipedia.org/wiki/Aircraft_registration (bottom of page)

That site has links to all major countries registrations.
