If only we had more than one datacenter.

You can keep multiple copies in different locations.

For me it's a bit of both. A programming book that I wrote over 10 years ago - the content is long out of date but the weight reminds me of the effort I put into producing it. Then there's my father's library, all 2000 books of it. I've kept about 50, on a wide variety of topics, and I value them both for the unusual content (Ancient churches of Wales; Jazz record catalogs from the 1940s; English artists from the early 20th century) and for the fact that they remind me of him.

> I don't love my books for the content, but for their essence

Curious thing to say. For me it is obvious that the content is the book’s essence.

... But you'll need a second house!
