The website hosts several types of spectral libraries and several versions of each. Users can either quickly toggle between library type or make use of a more comprehensive list.
Toggles to quickly switch between the type of library persist on each screen and are either displayed as a set of radio buttons or as a set of links. Toggling switches to the last selected version of the library.
Versions brings up a comprehensive list of available
spectral libraries and versions. Selecting a radio button sets the
corresponding library and version. For each library a short
description is provided, the date it was compiled and the number of
species it contains.
