The Austrian National Library Process

Work on an effective deacidification process for bound newspapers began in the Austrian Library in 1973. The technique, which has been in regular operation in Vieima since 1987, involves immersion in an aqueous solution of calcium hydroxide and methyl cellulose. Borax is then used as deacidification agent. 

Library has successfully applied the technique to various other archival materials. The current capacity is 3000 bound volumes per year.
