books are for use

Books are for use.
Every reader his [or her] book.
Every book its reader.
Save the time of the reader.
The library is a growing organism.

the order of its catalogue

I am unpacking my library. Yes, I am. The books are not yet on the shelves, not yet touched by the mild boredom of order. I cannot march up and down their ranks to pass them in review before a friendly audience. You need not fear any of that. Instead, I must ask you to join me in the disorder of crates that have been wrenched open, the air saturated with the dust of wood, the floor covered with torn paper, to join me among piles of volumes that are seeing daylight again after two years of darkness, so that you may be ready to share with me a bit of the mood – it is certainly not an elegiac mood but, rather, one of anticipation – which these books arouse in a genuine collector. For such a man is speaking to you, and on closer scrutiny he proves to be speaking only about himself. Would it not be presumptuous of me if, in order to appear convincingly objective and down-to-earth, I enumerated for you the main sections or prize pieces of a library, if I presented you with their history or even their usefulness to a writer? I, for one, have in mind something less obscure, something more palpable than that; what I am really concerned with is giving you some insight into the relationship of a book collector to his possessions, into collecting rather than a collection. If I do this by elaborating on the various ways of acquiring books, this is something entirely arbitrary. This or any other procedure is merely a dam against the spring tide of memories which surges toward any collector as he contemplates his possessions. Every passion borders on the chaotic, but the collector’s passion borders on the chaos of memories. More than that: the chance, the fate, that suffuse the past before my eyes are conspicuously present in the accustomed confusion of these books. For what else is this collection but a disorder to which habit has accommodated itself to such an extent that it can appear as order? You have all heard of people whom the loss of their books has turned into invalids, or of those who in order to acquire them became criminals. These are the very areas in which any order is a balancing act of extreme precariousness. “The only exact knowledge there is,” said Anatole France, “is the knowledge of the date of publication and the format of books.” And indeed, if there is a counterpart to the confusion of a library, it is the order of its catalogue.
