Updating news archives: Rick Paulus writes that outdated “trapped-in-time” news segments don’t tell the whole story.

“Creating detailed stories from the splinters of larger narratives is at the core of news gathering,” he writes.

“Journalists are charged with determining the scope of stories — where they begin and end, how broad or narrow a story should be. That challenge is now complicated by digital duplication, infinite archives and instantaneous access to them.”
