Ryan has a point. Ever since online companies have attempted to improve upon reference books by making them up-to-the-minute online resources, they risk the quality of the information it’s their job to supply, while trying to keep their info-hungry readers satisfied.

This is particularly a problem for Wikipedia. And for Google Maps, one can imagine the difficulty of providing users with clear border information for areas where there may still be border disputes. That’s a problem atlas publishers have generally avoided, since there’s room for dust to settle between their publication dates.
