[78-L] 78 RPM Record Guide by J Edward Prince

[agp]

Several years ago I got a copy of the 78 RPM Record Guide by J Edward 
Prince. For the uninitiated it lists 78s from 1945 on into 1960s. I 
have found it to be a nice tool for some of my research into whether 
or not sometiing exists on a late 78.

Mine is the 2005 edition. Does anyone know if he had a later edition. 
Also can anyone advise on resources for getting later editions
