I am of the understanding that buying books online is hardly worth anything because you don’t actually own anything. Maybe you own the digital file? I’m not sure. I don’t trust the longevity of it, though.
I’m told a lot (mainly by my Dad) that its a good idea to print those out to keep them. However, I’m talking about books that are easily 200+ pages.
I don’t know if its worth the ink or money to print them out. At that point would it be better to just buy a book?
Just buy physical copies of the books you really want to make sure you keep.
Printing out eBooks would cost way more plus you’d need some way to conveniently store all that paper in the proper order. Maybe something like a bound book.
