[KS] Is there one full good source in English on Korean Left(s), past and present?

Adrian's mention of Daegu reminded me it had been a hotbed of anarchist movements during the Japanese 
period and that made me think of Yi Yuk-sa who was involved in that, and indeed in the online Memorial Hall 
for him there is a listing of groups in Daegu from that period 
http://www.264.or.kr/?doc=html/work/index03_3.htm  It does not answer the broader question, but it might be 
of interest.
