Causes of deterioration and various methods of treatment of palm leaf manuscripts are described. Palm leaves used for writing, either the thick and nonabsorbent <i>tala</i>, or the thin and paper-like <i>sritala</i>, are subject to deterioration caused by improper handling or storage, brittleness, and insect damage. The text can also become illegible. Treatments described include fumigation with thymol and paradichlorobenzene; methods for making a text legible again; chemical or mechanical cleaning of the leaves; separation of leaves which are stuck together; and lamination.
