It used to be the case that my favorite, though rarely used (because it’s pretty mean), put down in cases where someone disputed the veracity my statement was to say, “That’s because this information is hidden… in books.”
Will I live to see when that is no longer the case? When the truest information (please, no discussion of epistemology here) is no longer in printed books but online?
But I’ve already moved away from books, haven’t I? I found that article online and I published this post online. Is everything I do undermining what I proclaim to treasure?

You might be very right, just look upon numerical libraries such as Gallica, Europeana, World Digital Library or Google Books, they all contain the worldwide heritage of knoledge, so in the near future books might be something unusual and the remained books will we in the museum, just like archives are today.
