During the transition, both viewers will be available for a short time. We encourage you to start using the new viewer for your work now to familiarize yourself with content before the old viewer is no longer available. Most major functionalities are preserved from BIOS 5 to 6. You will be able to move your selections between BIOS 6 and RareFind. In RareFind, the BIOS tab will have a radio button in which you can choose to open BIOS 5 or BIOS 6.
We have provided a full user guide (PDF) for you, as well as a condensed version of basic functions to help you get started (PDF). If you have questions and comments about BIOS 6, you can submit them to BIOS@wildlife.ca.gov.
