NRSV Review . The cover is too floppy and the pages too thin.  This makes it difficult to flip between pages.  Also, in the middle of the book, the pages were cut incorrectly (they are folded over).  I would not buy this again and as a matter of fact, will need to buy another version to replace this

Ex Output:
NEG

MISREPRESENTATION: This is 1892 Deathbed Edition! . Although the poems are beautiful... and I certainly don't mean to bash Whitman with this 2-star rating... it's the wrong book. NOT AS ADVERTISED. This was supposed to be the original 1855 edition. That's what I expected, and therefore (in my mind) what I was paying for. The original 1855 edition, according to modern literary analysis, was the "strongest/purest" version. It was the true starting point of Whitman's own (and consequently America's) poetic awakening. Consisting of just 12 "perfect" poems, it was THAT edition which Emerson praised so highly.    Whitman never put out another book... just revision after revision, addition after addition, and edition after edition of Leaves Of Grass... until you wind up with "the deathbed edition" which is a severely bloated and different work from the original.     I was very much looking forward to a slender volume of the original edition. Which is what the item description says this is. It's not. Be forewarned... it's the Deathbed Edition of 1892... nearly 500 pages. And frankly, there are MUCH better versions of the deathbed edition. Sturdier versions with nicer pages exist (this is a pretty weak paperback, printed on pulp pages), with better footnotes and more authoritive introductions. Shop around.     To sum up... the 2 star rating is because lying about which edition this is, is a terrible way to sell the book. Whitman was fantastic and the poetry contained in the book itself is first rate. It just would have been nice to get what I paid for. The "true" editon, written by a YOUNG Whitman at the height of his powers..

NEG

5 stars are not enough! . This is surely one of the greatest collections of 'linked short-stories' ever written -- it matches Calvino's COSMICOMICS and Borges' LABYRINTHS. Lem is a total genius. A writer of playful little fables that are also philosophically profound (and logically consistent). This book is a brilliant companion to Lem's THE CYBERIAD, with which it shares many themes and ideas. Lem has a beautiful style: he can make engineering terms sound poetic. His rigorously modern metaphors are as original as those of J.G. Ballard, but more varied and lyrical. For Lem, the Periodic Table is an unwritten poem. This book is the final and true ode, and each line is a fantastic, fabulous, incredible story. I give this book 200,000,000 stars. And that's only because I'm not feeling so generous today. It probably deserves A GOOGOLPLEX (1 to the power of 100 raised to the power of 1 to the power of 100) of stars. At least
