I have found the original documentaries produced _during_ the era itself to be the best way to introduce undergrads to McCarthyism (and they reward in other ways as well). Try the CBS _SEE IT NOW_ programs produced and aired from October 1953 to April 1954: "The Case of Milo Radulovich" is a frightening case study of guilt by association; "Argument in Indianapolis" concerns the ACLU and the American Legion controversy over free assembly; "Report on Senator McCarthy" is Murrow and Friendly's direct assault on the force at the center of the McCarthyism movement; "McCarthy's Reply" aired on SEE IT NOW shows the Senator confirming, in his attack on Murrow, what all his critics long suspected about his tactics; "Annie Lee Moss Before the McCarthy Committee" is charged coverage of the abuses of the McCarthyite's "investigative techniques." Aside from introducing the students to the original figures in the era, the documentaries ALSO reward by showing examples of _SEE IT NOW_ the earliest and seminal documentary series and represent a means to suggest comparison with techniques and aesthetics of documentary practice today. The "McCarthy Report" and "Reply" programs were slightly edited and included on a forty minute 16mm film available from McGraw-Hill films. I have seen this film in public library collections and media centers in many places so I would think that you should be able to find it without much difficulty. The other programs have a much more limited circulation.
