I think the American Heritage Dictionary (1969) was the first general dictionary to show reconstructed Indo-European etymologies for English words [1, 2]. That’s where I learned about the supposed common origin of “science” and “shit,” more than forty years ago. The first and second editions of the OED did not show many (any?) Indo-European roots, at least as far as I can recall, and they may not have been incorporated fully yet into the current online edition either. It’s also possible that the OED editors are cautious about accepting Indo-European etymologies, which are reconstructed rather than based on written evidence.
