Someone should create wiki or something so when people find these they can post in topics.<p>For example:
Topics:
-Math
--Discrete Math
--Statistics
--Graph Theory
-CS
--Data Structures
--Algorithms<p>etc etc<p>That way when someone is interested they can go their find the topic, find the papers and read them. Otherwise you've gotta go to Stanford's, MIT's, Harvard's, Berkley etc etc just to find any of these open courses. Its mostly a hassle.
Real Analysis and Abstract Algebra textbooks at <a href="http://www.mth.pdx.edu/~erdman/" rel="nofollow">http://www.mth.pdx.edu/~erdman/</a>.<p>Both textbooks were written by John Erdman under a creative commons non-commercial license. They were recommended to me by a math professor and both books are really high quality.
If you know of any other high quality, advanced undergraduate or graduate level courses in these areas, please leave them in the comments and I'll update the list.
