Note: Starting with version 6.0, Amphibian Species of the World will be updated in real time and can even vary from hour to hour, which means that citations will have to specify a year, and for purposes of citation and supplemental data authors will have to make permanent archives. They can be constructed through http://www.archive.org. Previous subversions (i.e., modifications of individual records) can be accessed using the Wayback Machine (http://archive.org/web/web.php).
