WHILE I AM GLAD THAT Washington City Paper ran my“Adieu to the District” (1/6), some things have occurred since I wrote that piece that beg to be added to my “Reasons I Am Sad to Leave D.C.” Two things, to be precise. The recent deaths of two friends, to be even more precise. They just happen to have been two of D.C.’s kindest (read: less abrasive) used- book sellers. These would be Bill Kerr, who ran Capitol Hill Books (near Eastern Market), and Alan Fuller, who co-ran Fuller and Saunders (in Georgetown). They both loved and lived for books, and were two of the more pleasant people with whom to spend time basking in mutual bibliomania. Though Bill and Alan will be sorely missed, they are survived by more than their immediate families. The many fine books they sold will continue to touch the lives of their even more plentiful friends and customers.
