The only thing Americans seem to like to do more than make money is spend it on stuff—but are we a nation of pack rats or archivists? Expert on collecting and author of In Praise of America’s Collectors Arthur Warren Schultz will answer that and other questions tonight about what has become the country’s most popular leisure activity. He’ll share tips from his book, as well, a highly readable mélange of history, anecdote, and advice on collecting, mainly from the world of fine art but extending into the arena of contemporary collectibles as well. In it we learn that Rembrandt, whose paintings are worth millions today, died bankrupt. Was it any coincidence that he was a collector? At 7:30 p.m. at the Corcoran Gallery’s Hammer Auditorium, 17th & New York Ave. NW. $15. (202) 639-1770. (Daniel Searing)
