Example text

It is soluble in water and is alkaline;in IO per cent aqueous solution it has a p H of I I. Tissue paper sheets impregnated with this solution may be used for interleaving documents or wrapping them, even in rooms which are subject to mould growth. They may be laid on shelvesprior to arranging volumes and documents on them and also used for covering the tops of documents in such rooms. Recommended on the basis oftests by laboratories engaged in conservation work,it was utilized by the author in Florencein 1969,and a large number ofdocuments damaged in the I 966 floods have been effectively protected by this compound against fungus growth.

Once hatched, the larvae eat their way to the interior ofthe book and return to the surface when prepared for the chrysalis stage. Finally the fully grown beetle emerges. Psocids or booklice Sometimes confused with the bookworm, these are pale, minute insects seldom found on books which are constantly in use and noticed only when they occur in large numbers, They feed on starch and glue in book bindings but because of their small size do little real harm.
