Here is the actual SCP Foundation website:

http://www.scp-wiki.net/

It's a collaborative fiction project.

It's a wiki project that contains the data files on strange, dangerous, and paranormal objects contained at the SCP Foundation. SCP stands for Secure Contain Protect.

The files range from creepy, to funny, to downright terrifying. A lot of the flavor comes from them being written in an incredibly dry way (extremely clinical) but with a lot of the important details redacted.

It's a very very cool website to browse around.

Here's the in universe description of what the Foundation is.

And here's an FAQ for the website. It's mostly targeted at potential authors wanting to join the site, but can shed some light on things.

Keep in mind that neither of things things are required reading (well, unless you want to join the site as a contributor). It's probably more fun to dive in blind, and learn as you go.

A few other things of note:

• Although there is no official canon to the website, many of the SCPs will connect together and link to each other. So it's very easy to run into the way situation you would while reading wikipedia where you'll be reading one article, then link to another to fully understand this one, and before you know it you have 9 tabs open and can't even remember what you were originally reading.

• There are some stories also posted on the site. These, like the SCPs, range from terrifying to hilarious. One of my favorites is Duke 'till Dawn and falls under the hilarious category. It's the story of a decommission attempt on a certain SCP (sometimes, when a page gets deleted, they write it a good ending).

• The community has a very strong quality control mechanism. If a given article isn't up to standards, it's given a chance to be revised, and then deleted to make room for a better. If you want some insight into this click the "Discuss" button at the bottom of the page. It might kill a little bit of the magic for you, but there are some really interesting things in there.

• There's a lot of "in house" terminology used by the website. I don't think it's explicitly laid out anywhere on the site, but you'll pick up on it fairly quickly.
