Below are some web sites organized by researchers that describe the relationships between organisms and their naming conventions.

About Identification

When you need to identify the plants and animals in an area, you need identification guides. Eisenhower Library has some guides that you can check out. Perform a keyword search in the catalog using the word 'identification' and the group you are interested in. An example search would be insects identification.

To the right are listed some of the print guides that are available in the Science Reference Collection on C-level of the library, as well as some good web sites. Since the reference books can't be checked out, you may want to take pictures of the item you are trying to identify and bring them to the library. Some of these items aren't true 'keys' but do provide some identifying information.

Finding Articles

Search databases that focus on information about organisms. AGRICOLA focuses on plants and agriculture. PsycINFO includes literature about animal behavior. The rest are fairly obvious.
