This document contains a list of primary source links organized under different group headings for an in-class activity on the digital past for a history course. The links provide views of Washington from different time periods, including a bird's eye view from 1853, a sketch of Washington from 1874, and a photo of Duke Ellington's jazz ensemble from 1940. Some links also show alley dwellings from the 1850s and a market scene from an unspecified time. The activity aims to give students a sense of Washington's history through primary sources.
