Go to <http://www.wilhelm-research.com/> for longevity of current inkjet 
papers and inks, with and without glazing in most full inkset 
evaluations.  Generally, using some sort of glazing makes the most 
improvement, doubling longevity in many cases.  Using UV-filtering 
acrylic sheet often adds an extra 20-35% on top of that. 

I use Epson Ultrachrome pigmented inks that range from 50-100+ years 
under glass depending on the paper.  Use the papers recommended by the 
ink manufacturer.  Some will say that this acting as a shill for the 
manufacturer, but it is the only way of knowing actual "predicted" 
performance.  Other brands of inkjet paper will perform the same, or 
better (possibly worse), but how will you know unless someone tests them 
for you.
