The principal works for the identification of all living organisms--animals, plants, fungi, bacteria, and viruses--found in northwestern Europe are listed in this practical and accessible reference book. The new edition reflects the progress made since publication of the fourth edition in 1978, and features a succinct selection of the relevant recent and standard literature for use in identifying organisms of the region. Arranged by major groups, with the title first and the author and date following, the book facilitates the search for a reference to a specific topic. Also included are details of general guides to the fauna and flora and the faunal lists of marine biological stations. The references listed can be applied to a wide area, enabling biologists to make correct identifications of rare or new records of species previously reported in the literature of other countries.
