Databases are just one of the ways in which biodiversity issues can be explored. As a source of specimen data, they may provide users with information on a range of parameters aside from locality information. Linked databases may provide many layers of information, such as that found in some GIS systems. Some cautions are in order for anyone using any database.

1. Data is assumed to be correct, but providers are not responsible for typographical errors.
2. Identifications may not always be correct or may be outdated by current standards of nomenclature. If there is any doubt, then you should ask to examine the specimens.
3. Data is assumed to be copyrighted by the organization that holds it.
4. Acknowledge data providers if you use their data.
5. You should ask data providers if you can use their data in your project.
