Hello All,

I tried finding a similar thread on this but had no luck and my eyes are going buggy trying to look through all the past threads. So here goes.

I have an idea for a non-fiction book and have found some simliar books with the same theme published. I would like to know how I can find out how those books have done with their sales. Is there a way to look find out the sales history for them?

Thanks for your help on this.
