Well, this is a sort of meta-question; not about aviation itself, but on the study of aviation. I use to read Aviation SA with my Mac, and –very often– I would like to 'cut and preserve', for later reading, some interesting and instructive answers, for example those from Kämpf and other savvy veterans here...
I use to do that by cutting and pasting the relevant texts to 'Word', but the formatting is partially lost in the process. I'd prefer to save a graphic image of the full answer, but the very useful 'capture/selection' utility is limited to the size of the screen, and scrolling is not allowed...
Any helpful hints...?
With the commonality of Internet and ever changing nature of text, it is neither possible nor recommended that you preserve the state of an article/text/etc. which has chances to be changed/edited/updated.
The preferred way on StackExchange is this (see red circle polygon):
Then this question will be available on your activity page under favorites tab.
If you don't like this way and want to directly save the link to a question or answer, you can do this:
and then save the URL.
You could also try converting the pages to an e-book, perhaps with dotEpub [1]?
I have no specific experience with dotEpub, it was just the top google result. If it doesn't suit your specific case there are many others.
