Bloomberg has an interview with Angus Robb, a big wig at Asprey’s luxury-gift emporium on New Bond Street in London (a road full fancy shops for rich people). Robb apparently buys rare books on behalf of Prince Charles and folks in the rich and famous tax bracket.

“I rarely see my most important clients,” Robb says of the process that adds to the mystery of his passion. “I get a call and head off on the treasure hunt. It can take anywhere from one month to one year to find what they’re looking for.”
