Q: Is there a way to determine how many times a sample of my eBook on iBooks was downloaded?

Hi BoatBuilder2012,

Welcome to Apple Support Communities.

It sounds like you have a content for sale on iBooks or the iTunes Store and want to know how to check your sales. You can find this information from the iTunes Connect for iBooks webpage, as described in the guide below.

I hope this helps.
