In 2014, Firefly Books published the beautiful and comprehensive reference, World of Birds by Jonathan Elphick. Sales and reviews of the book were excellent: "The value-to-cost ratio makes this a worthy addition to the ornithology collection in most libraries." -- Booklist (starred review) "An excellent reference book that will occupy shelves in many libraries. For those needing just one general bird reference, this might be it. Highly recommended." -- Choice
