The OWI will make for some interesting reading.
But I'm heading out to a ballgame and have too many irons in the fire from now thru the weekend, to do any real reading : (

Have fun at the ballgame! :-) When you get time to read on that Wikipedia's article on OWI is probably a good place to start. They list some books by Allan Winkler and Howard Blue you might check for more information. If you have access to a government reading room or good library the National Archive's OWI records are available on microfilm from Lexis-Nexis.
