I've just figured out how to use Nielsen PubWeb to register the titles & details of the two new books. Once I like a book title to one of my remaining 9 ISBN's I have to obtain the barcode for the book before it goes to the printers.
For the first book the printing company threw it in for free, but now I've been looking at how to buy them. Along the way and half an hour Googling later I realised that you can just buy the barcode software.
1. Enter the ISBN and a few details and ...
2. Click "Export" to get the TIFF for the doc.
I found this one which looks quite good - called "Easy Barcode Creator".
