Such guides were made already in times when print was the most popular (or, to be precise – the only – form of a book). The chart was intended to help those who saw the book for the first time.
In times of the digital content pushing the books aside, these guides (although still hilarious – who doesn’t know how to do that?) are a warning. Don’t put the book away, or you’ll really need this kind of guidance sooner than you think.
