I purchased the book on-line as a download in e-book form at www.lit-verlag.de (LIT Verlag is the company name, and the e-book is the German version). Since I am a monolingual English speaking person, that presented a bit of a challenge. Here is how I handled it:
You can do "Control-F button" keyboard searches with the e-book making it easy to find names and dates you are interested in. You can copy the text associated with name/date you are looking for . Then you and simply paste the text into the free Google translator (German to English). Then just copy the result into Microsoft Word in order to save you results in a usable form.
I can confirm Martin Dostál's observation that not all that is presented is correct based upon the information related to my great-grandfather and great-grandmother. That said, the book offers a lot of information about the Jewish Community in Liberec/Reichenberg.
