I don't think that there is much chance of success in absorbing the
odor wafting up the stairs. Removing the odor in a large space means
moving a lot of air through some very effective filtering. Zeolites
or baking soda may work to a limited degree in a small, enclosed
space. No solution will work effectively if the odor is being
"renewed" by mold activity.

Clay cat litters and white crystalline cat litter (this is a silica
gel) will absorb moisture, which may reduce mold activity, but both
will quickly reach saturation in a large room. Again, a desiccant
could work well in an enclosed space where the addition of new
moisture was not a key factor.

One solution is to prevent the spread of the odor by stopping it
near the source. This could be done by creating a microclimate
around the odoriferous archive. A microclimate system could be
achieved either by using encapsulation in plastic bags (with oxygen
absorbers to prevent further growth of mold), or by creating a
sealed "tent" and controlling the tented environment with an active
microclimate control system.

microclimate control see <URL:>
