The volume is largely incomplete, as about 40 pages are missing. This is an amateur 'pirate' scan that has been circulating on the net for years and which WoTC has made its own, without improving OCR quality or implementing the missing pages. They are aware that these pages are missing but have been saying for years that the file will be updated as soon as the original material is available. Apparently, the only thing missing is the will to give those who want to buy this product, the COMPLETE manual. Shameful behaviour to say the least.
