[Koha] Fast cataloguing

[Deb Vincent]

Hi all
I have superlibrarian permissions, but don't seem to get the option to add 
a book through fast cataloguing. If I try to issue an item that is not in 
the catalogue, I get a message saying the barcode is not recognised, but 
no option to fast add. I have also looked in Circulations, and can't find 
a link there either.
Am I looking in the wrong places, or is there something I need to do first 
to enable fast cataloguing?
Thanks for your help.
