This is perhaps off-topic. I once found the table of contents of what seemed to be a very good and thorough book on operating systems, maybe associated with MIT. Unfortunately I lost the link. I know this isn't much to go off, but is anyone here aware of something like this, or does anyone have recommendations for a good textbook? Thanks.
