A new exhibit to document history from a first-person perspective has just opened at the National Archives in Washington. According to an AP writeup, "the material for the archives exhibit comes from letters, photos, paintings and audio and video recordings," and ranges from a 1775 George Washington letter to a video interview with Rep. John Lewis (D-GA) conducted just last week.
If you're not near DC, you can still view the exhibit here, in online form.
