   • 1887, James Rodway in Timehri; Volume I, page #306:

     Once inside, they begin to mine; there may be apparently nothing wrong outside, but when you open the book you find a hollow filled with insects, which have eaten almost all the letterpress, up to the margins. By keeping the shelves away from the walls and giving a little attention to wormy volumes, the Library may be easily freed from this kind of Bibliophage.
