Thanks. It's good of Fagin to put so many of his papers online. Seems Codd's papers are harder and harder to find.

I don't have anything of his before 1969. Regarding 'refining', I can't guess how long he was thinking about it or whether there were mis-steps that he didn't want to publish. IBM had him working on lots of other things for many years. It's pretty clear, though, that he had a very collaborative spirit and put his first two papers out for others to see, knowing he had a good base with lots left to do.
