If you're looking for literature, you can find several short stories here with accompanying grammar explanations and vocab lists: http://www.korean.arts.ubc.ca/k410text.htm
I read quite a few of these when I took the 410 class, and it was a nice eye opener to the world of Korean literature :)
I have no idea what Korean literature is like. Any recommendations?
The little dabbling I have done has been with Korean poetry. I'm not ready to read Korean literature yet. My Korean pen pal did tell me about this story http://jreidy17.wordpress.com/2014/08/06/korean-novel-dwarf/ A classic story is Hong Gil Dong (67 pages). He is sort of a Korean Robin Hood.
