SCP Foundation

It's Special Containment Procedures, not Secure Containment Procedures. If you get this wrong, people less kind than I will tear you apart.

Throughout the article, you refer to the SCP as some variant of SCP-(XXXX). The correct format is SCP-XXXX. Make sure that is fixed before you upload this.

A ballistic-proof meter* thick of glass, cube-like, is to be placed around SCP (XXXX) at all times

This is worded rather badly. If I'm interpreting it correctly, I think you meant:

SCP-XXXX is to be encased within one meter thick bullet-proof glass.

The footnote in that sentence would be better located in the Special Containment Procedures, however if you want to keep it as a footnote use this code: [[footnote]]Footnote text goes here.[[/footnote]]¹.

it is to be kept behind Foundation Administrator restricted doors.

I think you mean something along the lines of "Access to SCP-XXXX is restricted to Level 5(?) clearance.

SCP-(XXXX) is a book currently the size of War and Peace three times over

Use actual numerical measurements every time you can. A quick google search has showed that in this case, the book would have about 4320 pages.

but attempts to destroy the book has only resulted in failure

The Foundation secures, they do not destroy. Try "but attempts to damage the book have only resulted in failure". Additionally, in my opinion, the "indestructible anomaly" thing is really overdone. You need a good reason for it nowadays.

Researchers first attempts to open and read SCP-(XXXX) with D Class personnel resulted in [DATA EXPUNGED] corpses and rapid cell death.

NEVER expunge one of the main effects of an SCP.

A [DATA EXPUNGED] strike force

Again with the unnecessary redaction. Just say "A Mobile Task Force".
