I don't understand why this page lists she appears in Crusader #1? In the note below this series, the system lists she's in 0 issues. Also, she doesn't appear in http://www.comicvine.com/crusaders-1-crusaders/4000-109778/
I'd suggest searching on the Grand Comics Database (www.comics.org). They're gradually adding all the names of writers for the letters to the editors, etc. to their indexes. If the name you're looking for isn't already there, it's quite likely there's an Archie collector who might be able to locate the issue for you.
Jerry Bails' Who's Who lists jack Schiff was born in 1909 and died in 1999. He retired in 1967. It also lists he attended Cornell University. It lists there's more in Robin Snyder's "History of the Comics" #11 (sorry, I don't have a copy of that newsletter). See also http://marvelmasterworksfansite.yuku.com/topic/12313#.UugN2mco5Ms
