And yet the city is not dead: the machines, the engines, the turbines continue to hum and vibrate, every <em>Wheel's</em> cogs are caught in the cogs… - Italo Calvino

In the shop window you have promptly identified the cover with the title you were looking for. Following this visual trail, you have forced your way through the shop past the thick barricade of Books You Haven't Read, which were frowning at you from the tables and shelves, trying to cow you. But you know you must never allow yourself to be awed, that among them there extend for acres and acres the Books You Needn't Read, the Books Made For Purposes Other Than Reading, Books Read Even Before You Open Them Since They Belong To The Category Of Books Read Before Being Written. And thus you pass the outer girdle of ramparts, but then you are attacked by the infantry of the Books That If You Had More Than One Life You Would Certainly Also Read But Unfortunately Your Days Are Numbered. With a rapid maneuver you bypass them and move into the phalanxes of the Books You Mean To Read But There Are Others You Must Read First, the Books Too Expensive Now And You'll Wait Till They're Remaindered, the Books ditto When They Come Out In Paperback, Books You Can Borrow From Somebody, Books That Everybody's Read So It's As If You Had Read Them, Too. Eluding these assaults, you come up beneath the towers of the fortress, where other troops are holding out:

the Books You've Been Planning To Read For Ages,

the Books You've Been Hunting For Years Without Success,

the Books Dealing With Something You're Working On At The Moment,

the Books You Want To Own So They'll Be Handy Just In Case,

the Books You Could Put Aside Maybe To Read This Summer,

the Books You Need To Go With Other Books On Your Shelves,

the Books That Fill You With Sudden, Inexplicable Curiosity, Not Easily Justified,

Now you have been able to reduce the countless embattled troops to an array that is, to be sure, very large but still calculable in a finite number; but this relative relief is then undermined by the ambush of the Books Read Long Ago Which It's Now Time To Reread and the Books You've Always Pretended To

So you begin to wonder if Leonia's true passion is really, as they say, the enjoyment of new and different things, and not, instead, the joy of expelling, discarding, cleansing itself of a recurrent impurity.

"And yet, in Raissa, at every moment there is a child in a window who laughs seeing a dog that has jumped on a shed to bite into a piece of polenta dropped by a stonemason who has shouted from the top of the scaffolding, "Darling, let me dip into it," to a young servant-maid who holds up a dish of ragout under the pergola, happy to serve it to the umbrella-maker who is celebrating a successful transaction, a white lace parasol bought to display at the races by a great lady in love with an officer who has smiled at her taking the last jump, happy man, and still happier his horse, flying over the obstacles, seeing a francolin flying in the sky, happy bird freed from its cage by a painter happy at having painted it feather by feather, speckled with red and yellow in the illumination of that page in the volume where the philosopher says: "Also in Raissa, city of sadness, there runs an invisible thread that binds one living being to another for a moment, then unravels, then is stretched again between moving points as it draws new and rapid patterns so that at every second the unhappy city contains a happy city unaware of its own existence.
