Item #: SCP-XXXX
Object Class: Safe
Special Containment Procedures: SCP-XXXX is to be kept in a reinforced room with 2 armed guards at all times. A security camera is to be watching SCP-XXXX-A at all times. No personnel below Level 3 are permitted access to SCP-XXXX without direct specification from Dr. Winter. All interactions with SCP-XXXX are done under guidelines set by SCP-XXXX-D.
Description: SCP-XXXX consists of multiple parts. SCP-XXXX-A is a large double door made of dense oak wood. It is roughly 8 ft in height and 6 ft in width with engraved imagery of landscapes. It’s handles consist of a rough iron circlet on each door. SCP-XXXX-A is unable to be forced open and appears to lead nowhere. SCP-XXXX-B is a similarly dense oak lectern with engravings similar to SCP-XXXX-A. Whenever a book is placed on SCP-XXXX-B, SCP-XXXX-A seems to react with a glowing light filled by slowly opening to another dimension similar to what is described in the book. SCP-XXXX-C are a small collection of books and writings (SCP-XXXX-C-1 through SCP-XXXX-C-3) written by “M” which have no records of existence.
SCP-XXXX-C-1 is titled “It’s Dark” which seems to be a short horror story involving a creature that eats light.
SCP-XXXX-C-2 is titled “The Old Gods” which follows the story of a town on a coast getting tormented by “Old, disfigured,giant, horrifying” creatures from the sea with abilities such as “mind control, telepathy, weather control,etc.”
SCP-XXXX-C-3 is [REDACTED]
SCP-XXXX-D, formerly D-9458, calls himself “E” or “The Librarian.” He came out of [REDACTED] and claims to be one of the safekeepers of SCP-XXXX alongside “M” who’s identity is currently unknown.
Addendum: SCP-XXXX is currently assigned to Dr. Winter Marie for research. As of current testing, it appears safe for subjects to enter as the dimensions are created similarly to our own. Testing has also proven that the events of a story do in fact play out in the dimension and can be interfered with. Interfering with the events has proven to rewrite the books and objects can be added and removed from the story via the door. Any items removed from SCP-XXXX-A is to be labeled as SCP-XXXX-D. Dr. Winter is currently awaiting approval to test SCP-XXXX as a possible method of containment.
Edit: It is possible that the dimensions created by SCP-XXXX are in fact permanent. That would mean closing the door simply closes the portal. Caution must be taken as to which stories are opened so as to not create a disastrous creature, being, or dimension that could find it’s way to our dimension. -Dr. Winter
Incident A - 11/16/2019
Subject: Exploration of SCP-XXXX-C-3
Procedure: 2 D-Class personnel, D-9458 and D-8672, are anchored via cable to the lab. SCP-XXXX-C-3, [REDACTED], is placed and opened on SCP-5883-B and the D-Class personnel are sent into SCP-5883-A as Dr. Winter Marie and 2 C-Class observers keep watch and 4 armed guards are stationed outside SCP-XXXX-A for safety.
Results: Only D-9458 made it back from SCP-XXXX-A and SCP-XXXX-C-3 is quickly removed from SCP-XXXX-B safely closing SCP-XXXX-A.
Analysis: SCP-XXXX, while easy and safe to contain, can easily be disastrous under improper usage. While D-9458 seems to have returned unharmed, something about him seems odd. An interview will be held promptly to gain further insight on the situation.
Interviewed: D-9458
Interviewer: Dr. Winter Marie
Foreword: D-9458 Survived SCP-XXXX during test A.

Dr. Winter: Hello. How are you feeling?
D-9458: D-9458 stares into the empty space
Dr. Winter: D-9458, are you listening? Is there something wrong? What happened in there? What did you-
D-9458: D-9458 seems to snap back to the present Where is M?
Dr. Winter: M?
D-9458: M. The Warden. They were supposed to be with the library.
Dr. Winter: You mean the author of these writings? Dr. Winter shows D-9458 the covers of SCP-5883-C We discover these abandoned with the door and stand in a basement.
D-9458: She left it? She- D-9458 pauses a moment Wait. You mean, you opened [REDACTED] without M? Do you know what you’re doing? [REDACTED] isn’t just a book, it’s a prison! You’re lucky I’m the one who escaped! There are creatures in there beyond your comprehension! You must not mess with the library. Let me take it off your hands before you create a disaster.
Dr. Winter I’m sorry but we can’t let you do that, It is our job to contain things like this.
D-9458: D-9458 looks around the room and at the camera. He takes a moment to think Well if you won’t let me have it, at least let me stay with it for safety.
Dr. Winter: I will see what I can do but you will have to go through a few tests and safety checks first. May we get your name as well as what you are and how you got here?
D-9458: Sure. I guess I can cooperate. You can call me E, I am the librarian. I was in [REDACTED] for reasons I would rather not say at the moment and I got here by transferring my consciousness into this host. No worries though, this body was empty when I found it. It seems this poor man ran into the soul stealer. Now if we may, let’s get these “safety tests” over with so I can show you how to “contain” the Library.

Closing Statement: D-9458 is promptly taken for safety examination and mental evaluation and is now identified as SCP-XXXX-D. SCP-XXXX's containment procedure is updated.
