Earth has become a library planet over the last several thousand years, a bastion of useful and useless knowledge-history, science, politics-gathered by 'pack rats' who scour the galaxy for any scrap of information. Knowledge is power, knowledge is wealth, and knowledge can be a weapon. As powerful dictators come and go, the cadre of dedicated librarians is sworn to obey the lawful government-and use their wits to protect the treasure trove of knowledge they have collected over the millennia.
