This reminded me of a different volume with lots of information on the Jewish community of Balassagyarmat, also including many victims' names. It seems to be published by the Nógrád County Archives and a related historical society. It is searchable, and if you copy and paste text into Google Translate, non-Hungarian readers can get a good sense of any section.

The same historical group has published at least three other works, covering different time periods and information in the area.
