This glossary (free) and list of materials (free) are part of the new Taxonomy Guide (fee-based) from the iSchool Institute at the University of Toronto.
The iSchool Institute goes on to explain that The Taxonomy Guide is both a reference resource and a learning tool “designed to help you master the concepts, relationships and essential steps for taxonomy design and project planning.” Topics covered in The Taxonomy Guide include taxonomies in context, taxonomy basics, software tools, design, and planning. The guide is designed for knowledge workers, records managers, librarians, information architects, and other information professionals. It can be purchased for $199 US.
