Cameron countered with a helpless shrug and smile. "I'm afraid I'll have to depend on your good nature to guide me through such a mass. I don't intend to become a student of Markovian history, of course, but perhaps you have adequate summaries with which a stranger could start. Going backward, let us say, for perhaps two or three hundred Terran years?"
"Of course—some very excellent ones are available—" He moved toward the reading table nearby and began punching a selection of buttons.

There were endless accountings of trading and commercial treaties between members of the Nucleus as shifts of economic balance occurred. There were stories of explorations and benevolent contacts with races on the outer worlds. Details of their most outstanding scientific discoveries, which seemed to come with profligate rapidity—
