Yeah, when you own the copyright for a book, you generally keep close tabs on the PDF file. Not that I don't trust you, Ian.
We spoke to our lical postal manager yesterday and apparently USPS jas instituted a two week quarantine for all packages traveling internationally, because of the virus. Funnily enough, though, the government has not made a similar rule for FedEx or other companies.
I get that and I did not really mean that you would send a PDF but rather send a secure digital file. Security concerns would be valid.
“Golf Course Architecture”, as an example, uses an app called “PocketMags” and both the delivery and the reading works very well.
Stead of backing up a truck to TC with hundreds of books then mailing them globally, you would have the option to simply “push out” the content to subscribers.
Sure, it’s nice to have books on the shelves in your golf library at home. But also nice to have everyone of your books with hi res graphics all in one place on a digital,device.
