Just curious - did you get the parallel version from an LDS (or “LDS friendly”) source? I assume you have the 1970’s version and not the 2 volume 2005-2008 version. Been wondering if the more recent version is worth the $20 each.
The parallel one was put out by the RLDS. around 1979, iirc. Plus I have another one from t2004 but not sure if it is Herald House or not. I can check for you when i am at the office. I also have a digital copy of the first edition.
I would say get several printings of it and compare. $20 per volume is cheap nowadays for any book.
Sorry taht was 1970, not 1979.
