From the introduction:
Moments are pieces of history, broken and scattered throughout time. The [characters] are able to preview these Moments and use the Sunblink cells to record them permanently.

Moments from the same region and era are more significant findings. Each researcher wants to build the most significant portfolio of recovered Moments and are even willing to steal for the distinction.
