It's coming, Judy. As much as we all love paper books, their day is done. I liken what's happening to my early days of writing. If you enjoyed a Slade book then, you'd write a letter and mail it to one of my publishers, who would send it to New York, where the letters would be gathered up and sent to me in a bunch, and I would write back about three or four months after you wrote.
Now, you go online and we talk in real time.
Paper books go out of print in the blink of an eye. As bookstores close, it gets harder to find what you want. But an e-book is available anywhere and never goes out of print.
So, it's coming...but it must be done right. Make the wrong move, and you're committed for the rest of your life.
