Foster's Guide to Middle-earth has no entries on East-mark and West-mark. I wonder if the author of the article meant Eastemnet and Westemnet? Sage 14:53, 20 September 2010 (UTC)Reply[reply]

They're metioned in the Unfinished Tales, I think. I'll look in the index. --Amroth
Edit: Yes, they're in the index under "Eastmark" and "Westmark". They're mentioned in the first page of the appendix of "The Battle of the Fords of the Isen" published in Unfinished Tales. --Amroth
