This is a catch-up review of a handy pocketbook I missed when it first appeared—much to my regret. It would have saved me hours of digging up information on new buildings and have been an indispensable companion on recent visits to New York. Having written an architectural guide to LA, and edited two others, I know how much skill and effort must have been invested in research, selection, procuring images, and writing succinct descriptions. Hill has chosen more than 200 buildings completed in the first decade of the 21st century in all five boroughs, plus a selection of projects anticipated for the second decade. What makes the guide a joy to use is the clarity of the layout, in which buildings are grouped in 22 districts and indicated on useful maps that also include subway stops. Scattered through the geographical coverage are break-out sections on public spaces, designer shops and restaurants, fire houses, memorials and other categories.
