Myself personally, I really prefer having a book in my hand. However, this year, due to finances, we’re using as many free books from Archive.org as possible. I am printing off the pages we need, and placing them in a duotang binder, so that I can still sit and read them, and have them in my hand. It’s not the same as having the book, but it’s definitely better than having to look at a screen.
Now, some might say that by the time you buy ink and paper to print things out, it’s just as cheap to buy the books. However, the difference is, I can print as needed, which spreads the cost out over the entire year, which is definitely easier on the budget than having to buy all the books up front.
