Where does Winston work and what does he do for

At work in the Records Department of the Ministry of Truth, Winston reads his daily assignments, sent to him in the form of small cylindrical paper rolls that spurt out of a pneumatic tube. The messages order him to "rectify" certain articles or news items to ensure the Party is always proven right and good, no matter its original predictions and actual outcomes. For instance, the predictions of the Ministry of Plenty's output of goods need to be "rectified" to reflect recently-published "actual" numbers. Once Winston completes assignments by dictating corrections into the speakwrite at his desk (which translates spoken word into written word), Winston puts all related documentation into a "memory hole," thus sending any evidence of altered data to a large furnace in the center of the building.
