Now the knowledge about historical events is almost automatically updated and hierarchically set in the Internet. All the new information we have to find in one place. We have many sources of information that describe one event from different angles. Finally, the technology allows to play back events, e.g. battles, which allows to better understand the context.
New technology may help historians and scientists discover new evidence. It might also let them study old evidence in a new way. This might result in errors being found and corrected.
