This is a book that should really be on your shelf if you are interested in finding your way around Swedenborg's voluminous works.
There is simply no better reference book for tracking down titles, figuring out when they were written, what they are about, and where they have been published.
But beyond this, there are fascinating and carefully written scholarly accounts of the subsequent history and impact of these works.
Knowing something of what it would contain, I got a copy as soon as it was published - but then I opened it and found many unexpected gems as well.
