Brief History

According to Hubert (2012), The Classification Society (then known as the Classification Society of North America) decided, in 1981, to establish a journal devoted to classification techniques. Following the work of several members – Hubert (2012) credits Douglas Carrol and Phipps Arabie in particular – the Journal of Classification was founded in 1984. The founding Editor-in-Chief was Phipps Arabie, who served from 1984 until 2011. There have been just three subsequent Editors-in-Chief: Willem Heiser (2002-2015); Douglas Steinley (2015-2020); and Paul McNicholas (2020-present).

Editorial Board

The current Editor-in-Chief is Paul McNicholas, a Professor and Canada Research Chair at McMaster University, Hamilton, ON, Canada. Members of the editorial board, including an editorial assistant and more than 20 associate editors, are listed here.
