There is a great deal of interest in the environment these days, and while much of that interest focuses on saving the world, a lot of it relates to learning about nature. Field guides are among the most popular natural history guides for the general public; it sometimes seems that almost every household must have at least one lurking in a corner. There are an incredible variety of field guides available for inquiring naturalists. The well‐known Peterson, Golden, and Audubon series and the typical bird, flower, and tree guides are just the tip of the iceberg.
