You can now buy it as an e-book or paperback from the original author: https://qntm.org/scp

If you like this, you should also consider reading qntm's other work -- I thought `Ra` and `Fine Structure` were particularly good:

Oh wow! I didn't know he was the same author. I've been looking all over for the Fine Structure website since reading it ages ago and lost my bookmark. Thank you!

Highly recommend. One of my favourite books from last year, probably the most surprising one. It reads like one coherent book, not just a collection of short stories.

I can highly HIGHLY recommend reading this. I blazed through it within 24 hours.

Favorite pun: "digitized" to describe being absorbed by a monster consisting of a mass of fingers...

Loved this series. IMO many scp hubs/stories are low-quality or have unsavory themes. This series avoids the worst of that and tackles a difficult problem in a thoughtful way.
