Actually this seems like a good time to ask this. I just went onto Amazon to see how much, and yeah, $150. But I noticed that for the original one there's a 40th Anniversary Edition that's only $25.
Does anyone know if all of the content is the same between the two? I can't see myself dropping over $100 on this but $25 definitely reasonable. Just wondering if it's a truncated version though.
I also kind of wonder if my library would have a book that's worth that much... I should check.
I think that one is a different, expanded or possibly collector’s edition. The one I got is this one.
