Correction: Directory of Foreign Firms Operating in the United States

Contrary to my hasty assertion in a posting a few weeks ago, I've learned (thanks to Eric) that you can indeed find a list of South Korean companies with operations in the United States. The Directory of Foreign Firms Operating in the United States does have a listing under "South Korea" (which makes more sense than my initial and embarrassingly rash assumption that such an entry would only be listed under "Korea"). The book can be found on Index Table 5B (Ref. HG4057 .A155 2004).
