What does A-F mean in LIBRARIES

Acid-free describes paper that is designed not to deteriorate, discolor, or become brittle over time due to the acidic content. It allows paper artifacts and documents to last for generations without compromising its physical integrity. Acid-free paper also contains special additives to create a neutral environment which helps to protect against damage from light, air and water.

Yes, acid-free paper plays an integral role in preserving the written words of our ancestors by protecting delicate documents such as legal forms, certificates, historical manuscripts and artworks from premature deterioration.

Generally speaking, you can check for acid-free properties in paper by looking at the packaging it comes in – often labelled ‘archival standard’ or ‘acid free’ – or if you are unable to do so, a simple pH test strip may give you some guidance as this will indicate its level of acidity.

No, unfortunately not all papers are made with an acid neutralizing additive and many contain some level of lignin which will cause them to deteriorate over time. Therefore it’s important to be aware and mindful when selecting an appropriate type of paper for any permanent applications.

When adequately stored in stable conditions between 18°C - 23°C (64°F - 73°F) and 30%-60% humidity levels, properly prepared acid-free papers can last hundreds of years without discoloration or embrittlement.

Typically you’ll find wood pulp based papers such as fine art papers or Bristol board boards suitable for printmaking being prepared using archival standards & alkaline buffers in order that they stay stable over time rather than becoming brittle with age.

This depends largely on the type of ink used however most quality dye and pigment based specialists inks should remain vibrant & resist fading when printed onto quality archival grade materials indefinitely provided they are kept away from direct UV lighting & damp conditions.
