What Books would you Rebuild Humanity with?

Books on a bookshelf by guldfisken

One of my favourite films is the 1960 classic (H.G. Wells’) The Time Machine. A 19th Century Scientist builds a Time Machine and travels forwards in time to see the progress of Humanity. Witnessing the destruction in World War II he travels further eventually seeing the 803rd Century and a Utopian society of gentle humans. But all is not as ideal as it seems.

The end of the film, without giving away any spoilers, he comes back to his present collects 3 books and returns to the future. If you were going to rebuild civilization what 3 books would you take?
