The shelves of books we haven't written, like those of books we haven't read, stretches out into the darkness of the universal library's farthest space. We are always at the beginning of the beginning of the letter A.

My books hold between their covers every story I've ever known and still remember, or have now forgotten, or may one day read; they fill the space around me with ancient and new voices.

Slothful, feeble, pretentious, pedantic, elitist - these are some of the epithets that eventually become associated with the absent minded scholar, the poor sighted reader, the book worm, the nerd.

Books may not change our suffering, books may not protect us from evil, books may not tell us what is good or what is beautiful, and they will certainly not shield us from the common fate of the grave. But books grant us myriad possibilities: the possibility of change, the possibility of illumination.

Maybe this is why we read, and why in moments of darkness we return to books: to find words for what we already know.

It has always been my experience that, whatever groupings I choose for my books, the space in which I plan to lodge them necessarily reshapes my choice and, more important, in no time proves too small for them and forces me to change my arrangement. In a library, no empty shelf remains empty for long. Like Nature, libraries abhor a vacuum, and the problem of space is inherent in the very nature of any collection of books.

If the book is second-hand, I leave all its markings intact, the spoor of previous readers, fellow-travellers who have recorded their passage by means of scribbled comments, a name on the fly-leaf, a bus ticket to mark a certain page.
