Wow, these are very good questions; If we go to the past we can see that the libraries were with books of another type of material, in papyrus roll forms, and a little older were blocks of stone or clay, such as the aforementioned great writing of Moses and his 10 commandments, If he lived for those centuries, he would think that the library has modernized its books, its material and its establishment.
I consider myself a person who lives day by day and I leave the future in the hands of God, but on occasions I have touched on this point with several friends, and we have imagined an AR technology library; although we ended up choosing a modern one like the current ones.

The criteria were reasonable between the differences:
When reading in the technological equipment, the light of the same, fatigued the eyes.
The font size was not appropriate and it caused eye pain.
There is no good posture in the user to be able to spend hours reading.
There is no total privacy for the reader.
We can't define the future of a modern library for sure, but the reader's convenience says it all. Inquiring about this issue today I got an article from the digital newspaper "el clarín". Which ensures that there is a bosque en noruega where they cultivate fir trees for the manufacture of books in the years 2114; I think that literature will not disappear because everyone who loves literature feels that pleasure of turning the page with their own hands, he feels that sigh of tranquility when feeding his mind on a story edited by a great author; And the authors will not lose their desire to fill a writing paper, to create their drafts on a stack of sheets or to achieve their success in a luxurious cover.
But, some of the ideas for the library of the future would be:
The books have a Qr code so that the reader who wishes to read it on their tablet or cell phone can obtain it by scanning said code, but when leaving the library the scanner is canceled to protect the copyright.
It can also have camping areas where families can share stories and literature with the little ones. There is nothing better than reading outdoors.
that's brilliant idea, a library with camping ground ! the future looks great if there's library with a camping ground.
Yes, well, I like being on the grass in the open air, it is more relaxing for both the reader and the editor, and also for the student. The mind is more connected to the imagination.
excelentes sugerencias para las bibliotecas del futuro....me gustó mucho tu idea de los libros en código QR...😉
