Amazon allows book data to be accesed for each of the following regions:
The current region source will be represented by a flag in the top menu.
You are welcome to change the region so Indie Book Discovery will display data from that Amazon region.
Sorry, but it's an Amazon thing as data is only available from some regions, even though you can buy books from other regions. We appreciate that it doesn't make any sense.
Even if your region isn't listed, links to all Amazon regions are still provided to enable you to purchase books from 'your' region.
