As stated in the "Note added in proof" to The First List of Additions and Corrections to the Glossary of Mineral Species 7th Edition (1995), a major revision of the classification and nomenclature of the Amphibole Group has been published in several mineralogical journals.
The classification of the Amphibole Group has been revised by a subcommittee of the Commission on New Minerals and Mineral Names (CNMMN) of the International Mineralogical Association (IMA).
