I am going to the library today to check this book out for the third time in 6 months. The copy that I get is a pretty new version. Has anyone had the opportunity to see both a newer version and an older version of this book? Forgive me for sounding cheap, but I can buy a used, older version online for $10 - $15, but a new(er) book is $30 or $40. I don't want to buy one of the older published books if it is very different from the newer publication dates. (And maybe they are exactly the same between the covers, just having different publication dates????) Many thanks. Have a wonderful day. It is beautiful here!!!
