EDIT Permanent paper Permanent paper is paper which meets the specifications of standards designed to ensure it will remain stable over long periods of time. This means that it will not discolour or become brittle with normal usage, such as examination and copying. Librarians and archivists have been campaigning for standards for paper manufacture and legislation to enforce its usage for all publications of long-lasting interest.

To preserve our documentary heritage it is important that the use of permanent paper increases. Acid-free permanent paper is no more costly than acid paper and is environmentally sound because alkaline paper mills produce less pollution and permanent paper is recyclable and biodegradable.

Some countries have developed their own standard, but a universal standard issued by the International Organization for Standardization (ISO) is now available: ISO 9706:1994.

Publications on papers meeting the ISO 9706 specifications can be recognized by this symbol or by the statement: \"this paper meets the requirements of iso 9706:1994, information and documentation — paper for documents — requirements for permanence.\"
