In October 1995, on p. 47 of this newsletter, I urged publishers not to go back to using acidic paper for their professional journals or other publications, if price was an issue, because acidic paper has such a short life, compared to alkaline paper.
As a compromise between high-quality alkaline paper that meets permanence standards, and the cheaper acidic paper with a high level of lignin that some publishers chose when paper prices went up, I recommended using buffered groundwood papers, which will last much longer and certainly cost less than acidic freesheet.
The research so far shows that carbonate can prevent or greatly retard the embrittlement of high-yield paper. It also slows the rate at which this kind of paper turns yellow, but can not entirely prevent yellowing. Another drawback, not a serious one, is that the alkaline reserve can be used up, if the paper is exposed to polluted air for many years. Research demonstrating this effect under accelerated aging conditions was reported in 1988 by the CRCDG, a conservation research arm of the French government. More recently, another lab has discovered that the alkaline reserve becomes ineffective when it is only half used up.
Here is a list of carbonate-filled high-yield papers which are probably suitable for journals and magazines. All of them except those made by Glatfelter are available only in rolls for web-fed presses. They are listed by the company that makes them. Larger orders can be placed at the mill, but small and medium-size purchases usually have to be made through a paper distributor or a company sales office; call the number listed and ask where and how to purchase the papers listed. Call the Abbey Publications office (512/929-3992) if there are any problems finding the right telephone number.
