"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?"

– Walter Benjamin, from "Unpacking My Library" in Illuminations
