For many groups of organisms, there is an external website that has an information page for every species. It would be helpful to include links to these external resources on the taxon pages. Most taxon pages now seem to try to pull content for the “About” tab from EOL, but there is often very little or nothing there. This would provide links to actual information.
For instance, fishbase.org has a page for every known species of fish. Amphibian Species of the World has a page for every amphibian species. Looking at the list of authoritative sources on the Curator’s Guide page, many of them include such pages.
