Even though today's manufacturers claim that modern glassine is of
"better" quality than the old stuff, i.e. of neutral pH and P.A.T.
certified, this does not address the real problem associated with
it: Should it ever get wet, it will become wavy and will stick
permanently to most photographic surfaces. Residues are almost
impossible to remove, with a permanent change of surface texture.
Inserting many interleaving papers into albums may cause stress to
the spine and should not be done without obvious need. I would check
first, whether the photographs' surfaces have already suffered: If
they have not during decades, why should they now?
