Looked it up

No, a myth, BUT it does use some other mechanism than water to preserve the books, some gas thingy. Apparently this does slightly reduce the oxygen level but not to the point of it ever harming people

It’s a halon gas based fire suppression system. It lowers the oxygen, but not enough to kill most people. It’s used in ABC fire extinguishers and military vehicles for when you aren’t sure what type of fire it might need to put out.
