- About Bookbinding -

One would think that the civilized world had had lessons enough, ever since that seventh century burning of the Alexandrian library by the Caliph Omar, with that famous but apocryphal rhetorical dilemma, put in his mouth perhaps by some nimble-witted reporter:-''If these books agree with the Koran, they are useless, and should be burned: if not, they are pernicious, and must not be spared." But the heedless world goes carelessly on, deaf to the voice of reason, and the lessons of history, amid the holocausts of literature and the wreck of blazing libraries, uttering loud newspaper wails at each new instance of destruction, forgotten in a week, then cheerfully renewing the business of building libraries that invite the flames. Nothing here said should be interpreted as advice not to insure any library, in all cases where it is not provided with iron cases for the books, or a fire-proof building. On the contrary, the menaced destruction of books or manuscript that cannot be replaced should lead to securing means in advance for replacing all the rest in case of loss by fire. And the experience of the past points the wisdom of locating every library in an isolated building, where risks of fire from other buildings are reduced to a minimum, instead of in a block whose buildings (as in most commercial structures) are lined with wood. You will perhaps attach but small importance at first thought, to the next insidious foe to library books that I shall name-that is, wetting by rain. Yet most buildings leak at the roof, sometime, and some old buildings are subject to leaks all the time. Even under the roof of the Capitol at Washington, at every melting of a heavy snow-fall, and on occasion of violent and protracted rains, there have been leaks pouring down water into the libraries located in the old part of the building. Each of these saturated and injured its quota of books, some of which could only be restored to available use by re-binding, and even then the leaves were left water-stained in part. See to it that your library roof is water-tight, or the contents of your library will be constantly exposed to damage against which there is no insurance. Another besetting danger to the books of our libraries arises from insects and vermin. These animated foes appear chiefly in the form of book-worms, cockroaches, and mice. The first-named is rare in American libraries, though its ravages have extended far and wide among the old European ones. This minute little insect, whose scientific name is the anobium paniceum, bores through the leaves of old volumes, making sometimes holes which deface and mutilate the text. All our public libraries, doubtless, have on their shelves old folios in vellum or leather bindings, which present upon opening the disagreeable vision of leaves eaten through (usually before they crossed the sea) by these pernicious little borers. It is comforting to add, that I have never known of any bookworm in the Congressional Library-except the human va¬riety, which is frequently in evidence. Georgetown College library once sent me a specimen of the insect, which was found alive in one of its volumes, but the united testi¬mony of librarians is that this pest is rare in the United States. As to remedies, the preventive one of sprinkling the shelves twice a year with a mixture of powdered cam¬phor and snuff, or the vapor of benzine or carbolic acid, or other repellant chemicals, is resorted to abroad, but I have not heard of any similar practice in this country. I may remark in passing, that the term "book-worm" is a mis¬nomer, since it is not a worm at all, but an insect. A more serious insect menace is the cockroach, a hungry, unclean little beast, which frequents a good many libraries, and de¬vours bindings (especially fresh ones) to get at the paste or savory parts of the binding. The remedy for this evil, when once found to exist, is to scatter the most effective roach poison that can be found, which may arrest further ravages.
