They were filled with hard-to-find volumes and vintage magazines about interior decoration, architecture, photography, art, fashion, the lives of society figures and of creators of all stripes—all topics I was interested in.

But I was getting nowhere. I felt out of the loop and out of favor. It took me a few months to realize that I was experiencing the impact of the recession on my line of work...
