I bought the Essential Jung: Selected Writings, selected by Anthony Storr, last night. So, not really what any of you suggested. But it has a fairly comprehensive introduction which gives an overview of his life and ideas, and then essential bits from various of his works. I think it will be good for a starter anyway, to browse through, and see if I want to go any further. Of course it's a bit bitty but I wanted an overview more so than anything else, even more than anything dealing specifically indepth with the personality types.
I browsed through that a bit last night, including some of the stuff about synchronicity - then was on the underground to work this morning, listening to Led Zeppelin on my MP3 player (haven't listened to them a lot for a while, though a little more again recently), and realised that the guy next to me was reading the famous book about Zeppelin, Hammer of the Gods. Ah, synchronicity. I love it.
