Several other websites provide good general narrative information about biodiversity and endangered species.

The following websites focus on compilations of information related to biodiversity. Some of the collections include digitized works, while others include numerous links to other useful sites.
A dizzying amount of biodiversity data regarding individual species is available on the web. These searchable databases and datasets are critical in many phases of biodiversity research. These databases are arranged by the variety of life forms included in the database. For instance, a website listed under narrow scope might include only trees, fishes, or reptiles, whereas items of broad scope will include a more comprehensive array of life forms.
