    I would not expect too long a life from any/most books in a domestic enviroment which in many respects is far less a standard than the preservation standards of museums and archives.

      The problem of acid free paper has mostly vanished. Most plain bond paper is now acid free because of changes to make it easier to recycle. Bond paper used to be filled with white clays but that is very difficult to recycle. Paper is now filled with carbonate compounds, mostly calcium carbonate. That neutralizes any trace of acid. The carbonates dissolve in acetic acid which makes it trivial to recycle, unlike silica mud. Current bond papers will last hundreds of years and more if protected from excess humidity and hungry fungi. Black laser printer ink will last about forever since the colourant is carbon black and in some cases magnetite/ferrite powder as well.

        I can't argue with that Evan but I guess it won't apply to "older books" - encycopedias and the like very much included.
