Thank goodness R. Levi Schneerson's letters weren't in Israel's national library

According to AP,

"Beetles chewed holes in hundreds of books at Israel's national library, but spared the rare and precious examples — including the letters of Albert Einstein.....
"The beetles usually don't eat modern books whose pages are treated with repellents, said [Rosalind Duke, deputy director of the Jewish National and University Library]. The wood-eating insects also don't like the taste of ink and prefer the binding and the margin of the pages."
