More's the pity, but it has been found necessary to "bug" the entrance to the Reference Room in Baker Library. "An electronic detection system has been installed," according to the more proper terminology, to reduce "unauthorized removal of books from the non-circulating collection of the Reference Room."
It works this way: Books somehow "preconditioned" set off an alarm if they are carried near or between two screens just inside the main door of the room. (Library personnel have been warned that the same noisy result will occur if books are brought into the room by the same approach.)
We are assured that the system is quite safe. Walking past the sensor, we are as safe as we are standing beside a radio, "safer than if near a television set."
