A delightful assembly of ""nouns of assemblage"" or venereal terms if you want the proper term for these multiple nouns along with some of their origins and variants. Even if the most tenacious birdwatcher never gets a chance to exclaim ""There goes an unkindness of ravens,"" there will be many others who will enjoy Mr. Lipton's tonic introduction and selection of some 200 collective words which are not just for that select ""brow of scholars."" In fact you might find an appreciative audience anywhere between a ""shush of librarians"" and a ""trip of hippies."" The attractive presentation, format paper, and precisely imaginative, and witty line drawings all contribute. . . A singular plurality of charms.
