This is a review of the error-ridden digital epub format and a caution to think twice before you buy it. (The book is rated 3 stars as the book.)
I'm reading this as a digital edition checked out through Overdrive from my public library. (The cover on Overdrive matches the August 2002 DelRay edition.) As a 1968 book being republished digitally, this suffers from a lot of problems, the main one being that no one could be bothered to proof what came out of the OCR (optical character recognition) before charging libraries or individuals money for it. Or even run it through spell-check.
Scannos abound such as "spedal" for "special" "dose" for "close" and r,m,n confusion turning up as alphabet soup. Then there's the punctuation problem. Virtually every sentence that ends with the letter "t" is missing a period which leads to re-reading for sense. There's no way the book went through all those physical printings since 1968 with these typos.
The kinds of typos inherent in transcribing to digital are well-known. Crikey, if publishers and the clearing houses libraries use are going to charge money for digital editions, they can at least invest 4-5 hours in making sure the edition is readable. There's no excuse for this sloppiness.
Full disclosure: I'm a volunteer for Distributed Proofreaders where people proofread old public domain texts for free and make them available for free. We take more care than this.
