Volume 21, Nos. 1 & 2 (1937) of the Bulletin of the Needle and Bobbin Club is devoted to a single study, "Notes on a Study of the Trade Routes of Central Asia," from material assembled by Rudolph M. Riefstahl and edited by his wife Elizabeth Riefstahl. It surveys the overland and sea routes between China and the West, with silk as the key commodity. Sections cover the beginnings of transasiatic trade, the Siberian, Ili-Dzungarian, Chinese Turkestan, Tibetan and minor routes, and the sea routes through the Indian Ocean and Red Sea. It includes three maps (A, B, C), photographs and plates, and a chronology of travelers.
