I just thought this was something interesting. Anddddddd its only from my limited expierence which usually narrows my mind. I Have a pocket phone book with phone numbers and addresses written in pencil in 1938 which is in perfect condition. I have photographs over 100 years old that are in perfect condition. I also have original government documents over 100 years old like birth certificates etc that were kept in a vault that are completely messed up. I also have copies of cheap post cards written 70 years ago that are in great condtion So my one way mind sees that government documents and papers are written on the cheapest paper available. I wonder where the money goes. Ema > Hello RickandRana, > For long term document or photographic storage then acid free paper is a must. The non acid free stuff goes brown and crinkly after a number of years ! Barry, thank you again for your time and help! We are reassured--- Rana
