The technical feasibility of including various types of graphic and sound in the product was tested by copying appropriate files from various sources. For demonstration purposes, certain of the files were copied onto the CD prototype and the hyperlinks hardcoded. Files of types *.gif, *.tif, *.wav and *.mov are represented. The three species selected for illustration in this way are European species of conservation significance and well-represented in Appendices to a number of international agreements: Steller’s Eider Polysticta stelleri, Grey Wolf Canis lupus and Polar Bear Ursus maritimus. The results were quite satisfactory.
