If you’re old enough to have American roadside memories, you may read this row of signs from last weekend’s Friends of the Princeton Public Library Book Sale this way: Book Sale/Saturday/Prices Low/Sure to Save/Burma-Shave. In fact, this table of History and Americana is being browsed during the Saturday afternoon calm following Friday’s tumultuous opening. Co-chairs Sherri Garber and Eve Niedergang report that this year’s sale broke last year’s record. (Photo by Emily Reeves)
