Review title: Black leather clad Elvis belting out his classics unplugged. Product review: Elvis never looked or sounded better. Reunited with his original band from the Sun Studio days, Elvis sits in an informal "unplugged" style setting and rips through some of the classics that made him a star. He reaches back to his country/blues roots to bring out the raw power of the kind of rock and roll he created. He's at his best when he has to improvise, especially when he wants to stand but the mic is too low. Elvis is like a fighter trying to unleash the musical fury inside.

Review title: a reader's review Product review: Frank Rowlett's story is an intense day-by-day account of life as a cryptanalyst in the Signal Intelligence Service during the years leading up to WW II. This story puts together important pieces of the historical puzzle. As a story, it is exciting, and brings history alive.This book was published as a well bound, hardback, dust jacketed book by Aegean Park Press, a publishing house well known for re-printing (keeping available and alive) important Cryptanalytical, Cryptological, Cryptograhic publications in softcover 8-1/2" x 11" format. Just the way this particular publishing house, who specializes in crypto works is treating this book "screams" the high regard they have for it.If you're looking for crypto course work, the how-to-do-it, Aegean Park Press has it, (though not in this book). If you are looking for the taste and feel, the heart and soul of real cryptanalysts enjoying their work, that IS the form & substance of this book; as well as being an important historical work.

Review title: Not sure what the aim was here...but it missed Product review: Not sure if this was a book to promote himself or explain the origin and inner workings of FedEx, but it was a pathetic mishmash and virtually unreadble. I now blame this guy personally when my FedEx overnight doesn't arrive on time.
