What did IMF records from 1944 to 1971 show about gold and the dollar?

Research question: What do central bank and IMF archives from 1944 to 1971 record about dollar-gold convertibility, reserve positions, and the pressures that built up before the 1971 break?

The available sources report that the United States held about three-quarters of the world's official gold reserves, which made the Bretton Woods system seem secure in its early years 2. The dollar was pegged to gold at $35 an ounce, with other currencies pegged to the dollar 1324. Pressure grew as foreign-held dollars outnumbered the U.S. gold stock by the 1960s 4, and sizeable U.S. balance of payments deficits fueled skepticism about the dollar's stability 18. The sources identify critical pressure on the U.S. gold supply after May 1971 currency disruptions as a tipping point, and Nixon suspended dollar-gold convertibility in August 1971 31. The facts provided do not include central bank or IMF archival documents from 1944 to 1971, so this answer is drawn only from secondary summaries and is partial.
