Congratulations on the release of your AD workbook. Based on what I've seen so far, it's very impressive and professional looking, and looks to include quite a lot of good useful information. My question is, will it be available in local bookshops at some point in the future? Say, all the way over here in Canada via Chapters Indigo? Tariffs are a major pain on the wallet.
I know you currently have no digital edition planned, but I would like to recommend in the future a digital edition that could be made available to those who purchase a physical copy of the book. This way, when the time comes in the future to make changes or edits, while it would be impossible to update the physical book without a new release, the digital edition could be easily updated at no physical cost to Serif. Plus, sooner or later, as much as we hate the idea, a digital edition will be made available illegally online. Beat them to the punch by releasing your own legal digital edition. it will most likely still pop up illegally online, but your users will be more likely to get it through you than risk their computers' security on questionable sites.
