A friend on Jewishgen who has traced his Galician [Brzesko]
KOENIGSBUCH family has sent me this URL:

microformguides.gale.com/data/download/1016000R.pdf

It does work but not directly.

It is the listing of the archives of the Wiener Library, London re
Holocaust testimonies.

I noticed quite a few Vienna/Prague references in it and also
and there is a ref. to Leonhard ZIMMAK [Sweden] re Commandant Seck
translated >from the German and Mrs Ernst STECKELMACHER document too:

Eyewitness accounts of the Rabbi Dr STECKELMACHER and his wife in
Germany and France 1933-1945 - 16 pages

Photographs include: Irma and Karl NEUMANN and son Zdenko - family
photos >from Czechoslovakia

Other names which caught my eye connected to our SIG area were KULKA,
Else KAFKA and Hans KLEIN [Vienna]

There is no index and you have to trawl through the many pages using
your magnifier and "find" function!

Tragic, but potentially valuable.
