Inventory of the Archives of the Middelburgsche Commercie Compagnie (MCC) ['Trade Company of Middelburg'], with a brief introduction and user manual. The MCC records are both a unique and, from a global perspective, crucial collection of documentary heritage, that allows a greater understanding of the slave trade in the so-called triangle trade from Middelburg, the capital of the province of Zeeland in the Netherlands, across the Atlantic in the 18th century (1730-1800). On May 25, 2011 the archive of the Middelburgse Commercie Compagnie (MCC) was inscribed on the UNESCO International Register 'Memory of the World'.
