There is a small body of literature on product tie-ins, but I'm not aware 
of any literature on the "Photoplay Editions" or similar publications.
Perhaps some other Screen-L participant can help out.
There is a book by Emil Petaja called Photoplay edition. San Francisco, CA
: Sisu, c1975.  
It is written from the perspective of a collector and includes a
bibliography covering the period 1914-1974.
