The chipendium is the official database for all chips in Sitekick. The chipendium was introduced sometime in mid-2005 with a new update. During 2005, the chipendium could only be activated permanently if the user had the chip #161 Tower. Later, the chipendium was automatically activated when a new account was created.
The original chipendium needed to be updated if the user had a chip not already logged. As well, the search function was not introduced until early-2010, with the new Sitekick update. The new chipendium now automatically logs all new chips in the totem, and storage (not trade).
