A. "Traditional", articulated keys, taxonomical / geographical arrangement ( B. Interactive keys )
These keys can be downloaded and used with an internet browser to keep the link functions, or (many of them) printed and used like a traditional, printed key. Several keys are presented with the internet adaptation developed by Tom Hollowell (Smithsonian Institution, Washington), whose cooperation is gratefully acknowledged. For further lichenological web publications see Zschackia.
