Long time readers of this weblog will remember this post about the first hardcover edition of Kate Grenville's The Secret River. The basic problem was that while the dustjacket carried all the book's identification - title, author and publisher - the cloth case did not. A few months later the second edition of the hardcover had rectified the problem and all was well.
Now, the latest novel from Peter Carey, His Illegal Self, suffers from the same problem. As bookseller Jack Bradstreet pointed out in a letter to "Australian Book Review" regarding the previous example, if the dustjacket is lost the book becomes unidentifiable on the shelf. Grenville's book was worse in that the cloth cover was fully black. Carey's novel at least has a printed photo on the cloth. Not much good if you shelve your novels with the spine out, however.
