located just beyond the lobby, the circulation desk—no longer a delivery desk—took center stage in Lawrenceville, flanked by turnstiles that admitted readers to the open stacks one at a time, under the librarian's watchful eye. To thwart thievery, the stacks were arranged in a radial pattern. On each side of the lobby were a general reading room and, for the first time in a library anywhere, a room for children... The reading rooms were separated by walls that became glass partitions above waist level—the better to see you with, my dear.
