There's Frederic Morton's books Thunder at Twilight
and A Nervous Splendor
. Those deal mostly with the upper classes, though. Likewise, Carl Schorske's Fin de Siecle Vienna
is mostly cultural history, mainly dealing with art, architecture, and politics, although there are some insights that might be helpful to you.
You might want to take a look at Brigitte Hamann's Hitler's Vienna
, which can give you a sense of what life was like for a lower class drifter in Vienna in the first years of the twentieth century. I haven't read it, but I've heard good things about it. You could also look at John Lukacs's Budapest 1900
, which isn't, of course, about Vienna or Graz, but which can give you an idea of what everyday life was like at the turn of the twentieth century in the Habsburg Empire.
