Two websites currently stand out for the access they provide to primary sources about the impeachment of Andrew Johnson in 1868. The first from Douglas O. Linder’s quite exceptional “Famous Trials” series. Linder, a law professor at the University of Missouri-Kansas City (UMKC) has put together invaluable primary source packets on trials from Socrates to the 9/11 hijackers. His archive on the Johnson impeachment trial is quite good and contains both primary sources and useful background information such as a timeline and bibliography. There’s not too many visual bells & whistles here, but the content is strong. A more professional-looking site and one that also contains significant content comes from HarpWeek. Their site relies on over 200 excerpts, including wonderful cartoons and images, from Harper’s Weekly magazine during the period 1865-1869.
