Thanks Glister.

Libby has a simple if rather juvenile interface, but yes, it works.

I now have the KA1 syncing books selected on the laptop.

The solution is in your aside "you can log in instead using Overdrive (an option is provided to do this, rather than using one of your library accounts)."

You must log in on the KA1 using your Overdrive account ID (email address) and password and then enter your library card number.

That makes sense as the system must need both details to tie everything together.

I think sync is now working via overdrive.com in the browser and the SA1 now shows as a registered device even if it identifies itself as an iPad.

Thanks again, Gilster. You have solved my problem. Perhaps the Kobo instructions should be more explicit!
