This is a collection of at least 4 books, all with the same Library of Congress number, same editor, but different authors. Our library has 3 books of the set. I have entered the other books manually without LCN. These are excellent, even after 60 years, as an introduction to habitats and ecology for middle school children. They encourage appreciation and observation of the world around us.
