To add to the information available about the fumigation discussion here are some basic references on pest management. Most of these were culled from information put together by Bob Child (Head Conservator, National Museum of Wales) who taught a course titled "Biodeterioration and Insect Pest Control in Collections" at our museum last fall. Zycherman, L.A. and Schlock, J.R. A Guide to Museum Pest Control. Washington: AIC and ASC, 1988. Story, K.O. Approaches to Pest Management in Museums. Washington, D.C.: CAL, Smithsonian Institution. 1985 Child, R.E. 1992 "Pest Mangement Strategy for Collections. Scottish Society for Conservation and Restoration Journal.
