What it does
The Encyclopedia of Greater Philadelphia publishes historical material about the city and its region, with themed background reading.
Follow a related-history link when a current regional story raises a historical question. The homepage connects subjects such as public art, institutions and slavery to longer historical material. That makes the project useful for tracing a local issue across time. Keep the regional scope in view when comparing it with a national account.
The project describes its coverage as a work in progress. A missing topic is a reason to widen the research, rather than evidence that the issue has no regional history.
