I do find a description of the book, one that continues from the link you posted with a simple Google search:
"Book will fill you with a love and appreciation of the prophet Joseph Smith and all the things he suffered to establish the Church. Being a compilation of historical data on the personal testimony of Joseph Smith, his greatness, his persecutions, and prosecutions, conspiracies against his life, his imprisonments and his martyrdom."
I guess we can take from that what we may...
When the book came out in 1952, it was quoted with amazing emotion from the pulpit in my little home town of Hooper Utah. I put up the link to AbeBooks because one can see from the list of offerings that it is not considered a collectors piece by the apologists or the numbers would not be $35-$100.
Virtually everything in the book is anecdotal with virtually no proof sources for things said. Just wonderful urban legends spoken in an emotional way.
I probably gave most of my 2 1/2 minute talks directly out of the book as a kid.
