Where can you find a fern identification guide?

The Discover Life website maintains a fern identification database that allows users to look up ferns by habitat, blade division, family and range in the United States. Fern Nursery has a similar database that classifies ferns that are likely to grow in British gardens.

Gardening enthusiasts or fern identification hobbyists may want to purchase one of the many books that have been written on fern classification, such as "Fern Finder: A Guide to Native Ferns of Central and Northeastern United States and Eastern Canada." The Nature Study Guides publishing company prints fern finder guides for every region in the United States and several other international countries and regions.
