Archival paper is an especially permanent, durable acid-free paper. Archival paper is meant to be used for publications of high legal, historical, or significant value. In the USA, such paper must also be approved in accordance with the ANSI standards. The international standard for "permanent" paper is ISO 9706 and for "archival" paper, the standard is ISO 11108.
Often, cotton rag paper is used for archival purposes, as it is not made from wood-based pulp. Thus, "archival paper" is sometimes broken down into two categories:
- Conservation-grade — acid-free, buffered paper made from wood-based pulp.
- Archival-grade (also Museum-grade) — cotton rag paper made from cotton pulp.

Famous quotes containing the word paper:
“There’s a long story, my friend. I never did like the idea of sitting on newspapers. I did it once and all the headlines came off on my white pants. On the level, it actually happened. Nobody bought a paper that day. They just followed me around over town and read the news off the seat of my pants.”
—Robert Riskin (1897–1955)
