A great source in English is the ‘pamphlet’ produced by the CPK called ‘democratic Kampuchea is moving forward’, can be found as a PDF online.

Most primary sources are in Khmer, but there are translations of many many primary documents; S-21 confessions, speeches, Revolutionary Flag issues and witness testimony at the ECCC (Khmer Rouge tribunal).

I have access to a lot of newspaper clippings from like 1969-1975 as well

i read First They Killed My Father by Loung Ung in school last year. its a very good book; a memoir from a victim of the whole situation.
