I deposited my novel with the State Library of Queensland today. They explain what is required of you and once you scroll down to the bottom of the webpage, there’s a link to deposit your eBook online. I was pleased to simply upload the file and it was done – hey presto. The library wanted a PDF version so I made sure that my PDF contained the ISBN within it. I was surprised that they preferred a digital edition over the paperback edition, but I guess everyone needs space. It certainly makes things easier at my end, and cheaper too!
Don’t forget to lodge your novel with your state (or country’s) library – it’s usually a legal requirement and at the very least, a lovely idea for our culture to collect all writings.
