Giambatista Bodoni, alias signorino Yambo, is a sixty-year old antiquarian book dealer. He suffers from retrograde amnesia and since there are two kinds of explicit memories, the semantic memory and the episodic memory, Yambo can remember things he read in books or was told - which are generated by the first type of memory - but not the things associated with his direct personal experience - which are stored in the second type of memory. He can't remember his wife Paola, his two daughters Carla and Nicoletta but he can recite countless quotations from the many books he has read.
So Yambo gets slowly acquainted again with his surroundings, his relatives, his shop and his pretty assistant Sibilla. But he can't remember whether he fell in love with her although he hasn't forgotten all the tricks of the trade he needs for shopping at international auctions for rare books. He is shown family albums filled with faces which mean nothing to him so that his entire memory consists of the books he has read. Then Yambo decides to go to their country house in Solara to try to trace back his childhood with the help of his "paper memory" since it is there he can find all his early readings.
Once settled in the attic of the Solara house, Yambo is surrounded by piles of books, magazines, cartoons, photographs and toys. He reflects on such topics as the articles in the "Nuovissimo Melzi", his favourite passages in books like "The Count Of Montecristo", "Huit jours dans un grenier" or the adventures of Buffalo Bill. He remembers the characters of his childhood, Captain Flint, Ciuffettino, Pipino, Sherlock Holmes, the Camicie Nere and the fascist propaganda. He listens to songs and anthems of the Mussolini epoch with the help of his grandfather's record collection.
And one day he stumbles upon a "Tim Tyler's Luck" album featuring a story called "La misteriosa Flamma della Regina Loana" which brings back the memory of his first love for a girl called Lila Saba whose features have haunted him all his life.
The imposing novel where Mr Eco shows what an erudite writer he is regarding matters of literature, politics, history and religion. The question of memory is important in this novel as Yambo realises that one cannot regard relics from one's childhood at the age of sixty in the same manner as one did when one was eight or thirteen. One of the pleasure of reading this book are the numerous illustrations which allow the reader to visualise Yambo's recollections.
