An inspiring result of dedicated work, this book brilliantly proves that even a small, long-settled and thoroughly developed area like the state of Rhode Island can support a beetle fauna that is rich beyond expectation and features many rare, poorly understood species. Yielding over 700(!) new state records, the study also allowed to add about 200 spp. to the fauna of New England, the most thoroughly studied area in the entire country (arguably, in the western hemisphere); see Sikes, D.S. 2003. The beetle fauna of the state of Rhode Island, USA (Coleoptera): 657 new state records. Zootaxa 340: 1-38 (Full text; can be considered a summary of the referenced book) and additions in: Sikes, D.S., and R.P. Webster. 2005. Bioinventory of Rhode Island Coleoptera: 45 new records. Coleopterists Bulletin 59(3): 311-327. The study also provides a lot to learn about sampling/collecting techniques –- and commitment to science. It puts Rhode Island on the entomological map big time.

An extremely helpful, thoroughly illustrated manual, one of the best beetle identification aids treating in-depth several tough and obscure groups, e.g., Cryptophagidae, Latridiidae, Demestidae, Ptininae, etc.; a must-have source for anyone dealing with beetles.
Besides identification keys that cover 120 spp. of 20 families, provides about 160 excellent detail drawings/SEMs, identification plates showing habita of 63 species and 64 full-page habitus drawings, general information on each family and each species treated, ample reference list, glossary, and index.
