How far back do your newspaper's online archives go? The U.S. Library of Congress has a database of thousands of newspapers dating back to the 1800s. In the case of over 150 of the papers, there are also digitized, searchable pages. And it's all available via its new Chronicling America API (technical details at our Chronicling America API profile).
Do you live in the now or keep a foot back in the past? Better yet, what should an API provider do? At the end of July Last.fm (our Last.fm API profile) shut off some old API calls, to the disappointment of some mashup users and developers. The company had some good reasons, but it raises the question about what developers should expect, especially from free APIs.
