In the center of Google’s campus lie a cluster of four buildings: 40, 41, 42 and 43. Contained within building 42 was the epicenter of product management: Jonathan Rosenberg’s office. Immediately next to his office stood a collection of three bookcases containing a library of different books on various topics that JR curated. I used to pass that library every day on my way to meetings and each time I walked past, I would pause to see which new volumes had arrived.
