As some readers might remember but others possibly not, the reason I used Amazon e-books is file format and their application / program for any any device (e.g. computer, phone, tablet) which allows books to be read anywhere a device is or can be taken, no matter what operating system.
Other folks like paper books which can be held in the hands, which includes yours truly.
The 6 months' worth (versus 3) won handily, so we're going that way. 📅
The results were so close between other choices, available will be:
▶ PDF and MSWord in both A4 and 8½x11" size, downloaded here (i.e. 4 options) 📄
▶ Amazon e-versions to be purchased as an e-book and hard copy, Amazon charges for the convenience, but their program application is free. (2 more choices, total of 6.) 📚
Gimme a week or two for the next edition to become available, folks. 😎
