Joyfull-
Thanks SO much for that first link!
I'd seen it (or something similar) during a Google search but couldn't get it to open.
I already bought the 1948 Encylocopedic cookbook (thought THAT was the one my mother used, but no), but am glad to see all the others.
I can't believe there isn't some info about Berolzheimer somewhere. So I'll just keep looking.
Thanks again for your help!
