Hundreds of small publications transferred from the general collections, including Linnaean dissertations and a botanical manuscript with hand-drawn and -colored illustrations, are taped or glued into old acidic “pamphlet” folders that need to be replaced.
Condition and treatment: Conservators will remove the publications from the acidic folders, dry-clean the pages and wash them in de-ionized water buffered with calcium carbonate (pH7), re-sew the publication with an acid-free paper wrapper, and make a custom-fitted, four-flap enclosure for it.
