The Little Book of Perfumes: 100 Classics, by Dr. Luca Turin and Tania Sanchez. This is the shorter version of Perfumes: The Guide, if you can’t stretch to the full, hefty book, focusing on what they consider to be the 100 greatest fragrances of all time – from Chanel No. 5 to Guerlain’s Jicky – although frustratingly, some of the featured scents aren’t available any longer, even if you Google them. (Including Coty’s Emeraude, Chypre, or Jacques Fath’s Iris Gris.) If you do own the original book, don’t bother with this – it’s simply the five-star reviews which featured in that.
