Last November, on p. 87 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, and can only be preserved at great expense. 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 of them chose when paper prices went up, I recommended using carbonate-filled high-yield papers, an economical type of paper that became available only within the last ten years. It will probably last much longer and certainly cost less. This is paper that contains lignin, sometimes a great deal of lignin, but it also contains calcium carbonate, an alkaline buffer that appears to stabilize the paper against the effect of lignin as it ages (browning, embrittling).
Actually, the research so far shows that carbonate can prevent or seriously slow down the embrittlement of high-yield paper. Carbonate also slows the rate at which this kind of paper turns yellow, but since it cannot prevent yellowing entirely, such paper cannot qualify as permanent by the standards used in this country.
(The permanence standards do not permit more than 1% of lignin because 1) when paper darkens, it is more expensive to microfilm or digitize; 2) important historical documents cannot be exhibited for very long, if at all, because they would darken, and the public would object to this apparent neglect; and 3) works of art on paper, and paper collectibles like old comic books, lose significant market value if their appearance changes.)
Here is a list of carbonate-filled high-yield papers which are probably suitable for journals and magazines. 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 bought 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 Newsletter office (512/929-3992) if there are any problems finding the right telephone number.
