his book is the users' guide to the International Code of Nomenclature for algae, fungi, and plants, specifically the Melbourne Code. The objective has been to create a text that is reasonably clear and simple,
using plain language as far as possible, to serve newer users of the Code as well as veterans who are not familiar with every arcane detail. The chapters are arranged for quick reference, e.g. important dates for
certain rules, how to publish a new name, how to find the correct name for a taxon, how to designate a type, or even how to try to change the Code itself. Subheadings, boxes, bulleted lists, tables, key words in
boldface, a subject index, and an index to scientific names help users to find information.
