The SCP Foundation is a fictional wiki describing paranormal objects or entities (each labeled SCP-##), written from the perspective of the "SCP Foundation", SCP standing for Secure, Contain, Protect. Each page describes a new object, research done on the SCP, and containment protocols.
It's a fun read and easy to get sucked down a rabbithole
SCP also stands for "Secure Containment Procedure" when used in the context of a numbered SCP, as distinct from the SCP foundation.
I really like this from the idea of conveying information - the containment requirements come first as they're most important. It's a useful thing to think about when writing and email. Also really like it as a global collaborative writing project.
