I only just started digging into Initiation into Hermetics, so far a good deal of the ideas and practices are resonating well with me. I've been reading a pdf of the 2001 Merkur Publishing edition on an e-reader, went online to download another copy for quick reference, and noticed that there were marked differences between what I had been reading and what I downloaded. The edition I downloaded was published in West Germany in 1987... when I noticed the difference I did a search and now see that there is also a new 2009 edition, completely re-translated from the original.
I don't know how much it matters, but has anyone experienced or heard about the differences in editions? Any reasons for reading one over another?
