1995-2003 Three volumes (complete). 410, 371, 572 p., numerous figures and photographs (some coloured), hardbound. Library stamps and small removed sticker mark on verso front cover, else very good set. The first volume is out of print.These three volumes have about 1300 pages, in which fifty authors from eighteen nations treat a huge variety of aspects. Taxonomy without a doubt dominates the WBC, and besides modern revisions, keys and checklists, almost 200 new species (and subspecies) have been described, along with nine new genera and subgenera. Detailed descriptions, including colour photographs and maps, of all collecting localities are provided. A key to the Chinese families of aquatic Coleoptera is illustrated splendidly with colour drawings, as are many of the chapters.
