Jarom, son of Enos, keeps the smallest and least eventful of the small plates books, explicitly stating that he writes only a little because, in his own account, there is not much to add to what his father and grandfather already recorded. What he does record is largely a summary: continued observance of the law of Moses, the ongoing presence of prophets among his people, and recurring conflict with the Lamanites, described in general terms rather than through any single dramatized episode.
Jarom's brevity is itself part of the record's design: each keeper of the small plates decides independently how much space his own generation warrants, and Jarom judges his own era to be one of continuity rather than crisis, which is why his book reads more like a note appended to the ongoing chronicle than a narrative in its own right.
Jarom also notes that his people had, by his time, grown numerous, built weapons, fortified cities and prospered under their kings, brief details that later Latter-day Saint readers concerned with Book of Mormon geography and archaeology have treated as significant despite the surrounding text giving them almost no elaboration.
Later Latter-day Saint commentary has sometimes read this bridge stretch as evidence that record keeping itself, not only the content recorded, was a spiritual discipline being modeled for later generations, an obligation each keeper takes up in turn rather than an incidental habit of a few individuals.
