As an amateur programmer and someone that's worked on huge databases for a living, I can say I learned quite a few things from this book that I didn't already know.
But,the book goes on way too long. There is a good long chapter on stock screens; all the other chapters are fluff.
If you want to know everything about stock screeners, buy the book and read that one long good chapter, skip the rest of the book. I don't know of any other stock screener books, so I give it 4 stars for being innovative.
If not, you might appreciate this book because it pertains primarily to Multex's premium screening program, a product costing over a thousand dollars. Given that the book focuses upon one particular and very expensive screening program, might it strike you as disingenuous to give the text a generic title like "Screening the Market"?
To be sure, the book's author does describe screening techniques for readily available free screeners. However, the techniques pertaining to the free screening programs offer nothing so much as a pungent contrast to the book's central focus on the superior power of the premium screener described by the author.
My advise concerning this book is to check it out from the local library before purchasing it, because chances are you'll resent learning that you must use the author's premium screening software to make the best use of the book -an issue that would be moot if there was some indication in the title, or even somewhere on the book's jacket, which alluded to the need for readers to employ an expensive screening program (as promoted by the author's firm) to make optimal use of the book.
