You could also try the Liverpool Central Library. They may have a copy of the book.
There is a copy of it for sale on Amazon - https://www.amazon.co.uk/LIVERPOOL-RECORDS-CONGREGATION-1836-1930-HISTORY/dp/B002OEJYPM
JCR-UK has some information about the Hope Place Synagogue which can be seen at https://www.jewishgen.org/jcr-uk/Community/liver10_hope/index.htm
Finally, there’s the Liverpool branch of the Jewish Historical Society of England. They may know of or have a copy of the book you are after - https://jhse.org/notice-for-liverpool-branch-members/liverpool/
Again, I hope this helps.
