They published under the joint name of Covens & Mortier. The business specialized in publishing French geographers. They also published atlases, for example a 1725 reissue of Frederik de Wit’s Atlas Major and an atlas, with additions, from the works of Guillaume Delisle. There were also Covens & Mortier pocket atlases and town atlases. The company profited from acquiring plates from other geographers as well.
