Please do not combine this entry with 'The Butterfly Book' of the Nature Library Series. These are separate books/series. & don't combine anthologies here.

From the dustjacket (quotes added for readability): 'The Little Nature Library' stands midway between the 'Nature Library' and the 'Pocket Nature Guides.' it is less detiled than the former, not so closely compressed as the latter. ... In other words each of the four volumes tells the most interesting things about the most interesting American varieties of the subject treated.
