[Hurricane Katrina] New Orleans, LA, 02-3-06 -- A FEMA funded "Voodoo" Helicopter drops a load of water on the 1915 historical landmark Coliseum Theater Fire. Low or no water pressure in some areas has made fighting fire difficult and FEMA has provided aerial water drops to help New Orleans Fire Fighters fight fires. MARVIN NAUMAN/FEMA photo

National Archives. Washington, D.C., Nov. 22. Preservation of documents has long been a problem in libraries and offices of record. It was once done by a process known as 'crepelining,' which consisted in placing coarsely woven silk over and under the paper to be preserved with the use of adhesive. The most modern process now used is called the laminating process and consists in sandwiching the document between two sheets of thin, transparent cellulose acetate. This is then placed between two highly polished metal plates and subjected to heat and pressure in a hydraulic press

National Archives. Washington, D.C., Nov. 22. In the powerful press, the sheets of acetate, under heat and pressure 'melt' into the pores of the paper and adhere to each other as well. One additional advantage of this process is that, after being pressed with the sheets of cellulose acetate, the paper is thinner and takes up less room than it did originally. The result is a sheet of paper and acetate which comes off the polished metal plates as a single sheet. Tests for the aging of this material made by the Bureau of Standards in Washington have shown that this treatment of the paper, called laminating is as permanent as it is possible to make any record of paper
