Having served as a librarian in public libraries and taught in universities, Miller (academic resources, Argosy U. Florida) argues that public libraries should continue their venerable tradition of leading the public, in this case, by helping the public connect with environmental awareness and education. The medium always being part of the message, she says, libraries need to exemplify environmental responsibility as well as promote it. She discusses the library's green role, the library as a green place, green services at your library, and the library as a green teacher. An appendix cites appropriate books and other works for children, young adults, and adults. Annotation ©2010 Book News, Inc., Portland, OR (booknews.com)
