Hello, Grand Sorcerer Sirtel!
Many thanks for the suggestions you have made. I will get Calibre 1.48.0 - even though it may not have all the latest bells and whistles; my needs are basic not NASA-related.
I also intend to get the version that suits Linux but I need to check on some details regarding its installation on my dual boot HP-Mini first. I seem to recall that it requires Python 3 to work properly on Linux. I will check with the Englishman who helped me create my dual boot system on how to proceed for putting Calibre on my dual boot system.
Thanks for your help and best wishes for the New Year!
