I put a copy of the paper here
CJ Crook paper, so you can see it however, its not on my website.

After reading the paper, it is difficult to dismiss the April 1 connection however, after reading DonM's comment below and Crook's reference to receiving one of his first Sudoku books on his 70th birthday in 2007.....

I went into Borders (a book store chain for those not in the U.S.) the other day and just for the heckuvit checked out the Sudoku section. There were easily over 100 Sudoku books with all sorts of names. While right next to them were books on Chess, Bridge with indepth descriptions on how to play them, not one of the Sudoku books had anything more than 1-3 pages on very rudimentary instructions on how to solve a sudoku puzzle (eg. pretty much limited to cross-hatching, perhaps basic naked pairs and the like.) and most of them had nothing. If you were lucky you might come across Paul Stephen's Mastering Sudoku which is probably the best book available for basic methods now that Andrew Stuart's 'Logic of Sudoku' is sadly unavailable now. Otherwise there's virtually nothing that would teach someone how to logically solve a puzzle. Which means that any person trying to get to the level of those on this forum have got a lot of hard-core sleuthing to do.
...it seems more likely that the retired Crook spent time wondering around a Border's bookstore in Winthrop, North Carolina where he had been a professor of mathematics. Applying his life long skills, he discovered naked multiples. From this view, DonM's words would seem to ring true. BTW, he published at least one paper with I. J. Good about 1980, "C. Crook, I. Good" ?.
Is it time for a large multi-volume compendium on
all the methods to fill Borders' shelves? I'll do the graphics.

Yes. A rather substantial area of computaional math and physics is based on what's called the Monte-Carlo approach. People familiar with Monte-Carlo but not Sudoku may have a different opinion about coin-flips.
Having said all that,
now imagine any of the experts around here sending such a paper to the AMS.
