An ever improving resource!
As of last January (2015), it listed 1100 courses.
Another fifty courses have been added and I discovered a course in Hittite!
The same problem with collating content across resources that I mentioned for data science books, obtains here as you take courses in the same discipline or read primary/secondary literature.
What if I find references that are helpful in the Hittite course in the image PDFs of the Chicago Assyrian Dictionary? How do I combine that with the information from the Hittite course so if you take Hittite, you don’t have to duplicate my search?
That’s the ticket isn’t it? Not having different users performing the same task over and over again? One user finds the answer and for all other users, it is simply “there.”
Quite a different view of the world of information than the repetitive, non-productive, ad-laden and often irrelevant results from the typical search engine.
