Conditions of use

The package and its components may be used and copied without fee, provided copies are not made or distributed for direct commercial advantage and the source is acknowledged. We would appreciate being informed of such applications.

Contributions

The database contains no original observations; the descriptions were merely compiled from readily accessible sources. Unlike those from many parts of the world, the flora and fauna of Britain and Ireland have been studied so extensively that, for many groups, it is possible to construct a useful database entirely from the literature. However, standard taxonomic publications are poor sources of reliable comparative data, and practical testing against living and/or herbarium material is sure to reveal errors and other inadequacies in the descriptions, and hence in the key. We would appreciate having these pointed out, so that they can be corrected without delay; and we would particularly like to hear from people interested in contributing to further development of the package. In addition to improving the character list and adding character and taxon illustrations, this could include extending the geographical coverage, or preparing separate accounts for other regions.
