Pros advise to change acid-free tissue and containers every
several years or so for continued preservation of contents. This led me
to wonder how do we know how fresh these items are when we purchase
them? What if they have been "hanging" around for a year or so before
being sold?
Does anyone know how vendors determine shelf-life of these
archival supplies to ensure us full-life value?
