In years past, The English Connection (TEC) has run several series of articles related to historical accounts of KOTESOL's chapters and its presidencies as well as of Korea and its education in times gone by. Three of these article series have been compiled and each put into an easily readable PDF for your reading convenience:
Korea of Decades Past, written in 2004, is a collection of four articles on what Korean life and education was like 10, 20, 30, and 40 years earlier.
Chapters in History, written in 2005 and 2006, is an eight-article series on the beginnings and activities of KOTESOL's eight chapters at that time.
Presidential Memiors is an account by KOTESOL presidents of their presidencies (1993-2009) in a collection of 15 articles.
Also, compiled is a series on individual KOTESOL members.
KOTESOL People features individual members for their contributions to KOTESOL and their interesting work and lives (2014-2018).
