VOLUME 8 NO.1 Archival Products NEWS Paper Splitting as a Preservation Option by Margit J. Smith

APER SPLITTING HAS BEEN practiced since the middle of the P 19th century. In 1901 Douglas Cockerell, in Bookbinding and the Care of , writes that “The paper to be split should be well pasted Paper splitting on both sides with a thickish paste, and fine has been linen or jaconet placed on each side. brought to a It is then nipped in the press to make the high degree of linen stick all over, and left to dry.

with the newest mechanized paper splitt- ing machine. Now, however, the process is used mainly as a measure to preserve printed material that has become too brittle or too fragile to be handled safely. This works because the paper fiber links in the paper to be split are weaker through acid content, or outside influences, than the links produced between the paper and the carriers attached to each side with a specially formulated adhesive. When pulled apart the weaker paper splits neatly I observed as in the middle. a two-person It is an astonishing process because very thin, very brittle paper can be treated team split these in this manner, even paper with holes large sheets by caused by iron gall ink corrosion.
