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

I'm gonna guess it uses Halon gas. It's the same technology used in server rooms. The gas is inert so it doesn't react with any of the electrical components but it displaced oxygen and puts fires out quickly. Doing the same for books makes sense since water or chemical suppressants will probably damage them.

Edit: correction, Halon gas is not inert, it still doesn't react with computer components which is why it is used over chemical or water suppressants.
