Book Preservation Dear VSG, I am a grad student at UC Berkeley currently researching in Hanoi. I He has a first-edition of Alexandre de Rhodes' Tuchinensis Historiae Thanks for the help, Martina T. Nguyen
Hi Martina, This sounds fascinating - I would try consulting with Pham The Khang, Cheers, Rob Hurle
Martina, Sorry I did not send you an response to your earlier message on this. I Lan at the Han Nom Institute, or Library Director Bac at General Sciences Best Judith Judith A. N. Henchy Hi Martina- As Judith mentioned, John Dean from Cornell University is a great resource. Good luck! -- The Institute of Han Nom studies, working with John Dean, has just published Mike Michael DiGregorio Dear Rob, One of the resources that you wish to avail yourself of is www.librarypreservation.org. This is a web-site that provides information on some of the preservation issues that you might be concerned with. One the sections mentions the following: Various methods have been used to eradicate pests, with differing degrees of success. These include ethylene oxide (ETO), methyl bromide, formaldehyde, and, more recently, gamma radiation. Most chemical fumigants require that the materials be enclosed, a vacuum chamber in the case of ETO and plastic sheeting or tarpaulins in other cases. Gamma radiation, used to deal with both insect and mold infestations, has the advantage of no residual effects a major disadvantage with chemicals but studies have demonstrated that gamma rays damage cellulose, the building blocks of paper. More recently, tests have shown the advantage of both cold and heat to kill harmful insects. Temperature manipulation is preferred to toxic chemicals. You may wish to try a couple of techniques. One method that works very well for small groups of books is heat treatment. Wrap the book(s) up tightly in black plastic and place it in a metal box that can be sealed. Place the box in direct sunlight for about 4 to 6 hours. Alternatively wrap the book in clear plastic and freeze for a couple of days. However, it is important to ensure that the book is conditioned (allowed to slowly readjust to ambient temperature after freezing) before replacing it on the shelf, otherwise mold can develop because of condensation. One method to effect this is by standing the frozen book on edge on absorbent paper and allowing a fan to blow constantly on the book to help sublimate the moisture as the book warms. In SEA, it is common to use formaldehyde mixed with water and heated to produce a mist which is piped into a sealed box, but this is not very good for the health of the operative. My advice is stick with heating or freezing as insects live in a fairly fixed temperature zone and it is comparatively easy to disrupt it. When the book is free of live insects, go through it with a soft brush and fan away any dead insects, larvae, and eggs. It may be that the insect damage was caused several years ago but do it anyway. Check the site for information on general care and housing. John
