I just got my 2007 edition copy of "Interpretation of Dreams" in the mail so I haven't had a chance to read it. So this rating is only on the particular edition that is published by NuVision. They did not include an index or any information about who translated this version. Also, the table of contents is nearly worthless; no detail what-so-ever about the chapters, not even titles of the chapters, just Chapter 1 etc. and a page number. Even though you may think a newer publication is better, this one is much much worse and more expensive. Go with the 1980 publication. I'm returning the book to Amazon (who gets 5 stars for customer service!)

With no harmful intentions toward the movie brassed off.(thats where the talk at the begining of the song tubthumpin came from)Thank God I don't have any guns. Otherwise I wouldn't be here to write this review. What is this bait and switch. I first heard tubthumping on the radio very most excellent. Or so I thought. I bought the CD hoping for some good British tunes and what did i get. Stuff the baby on the cover could have written better. Please save shelve space never make another CD in this genre.

Somewhere out there on this Earth, there are three other equally well-made chargers I've misplaced. Until I stop losing these illusive chargers, I will continue to buy them to feed my photographic addiction.
