I was disappointed in this purchase, because the of the frequent scanning/transcription errors that could have been easily caught and corrected. e.g. AUTOBIOCrLXPHY instead of AUTOBIOGRAPHY, as well as many that are indecipherable. A simple look through the text to correct the more obvious errors should have been done. A table of contents that is linked to the chapters would have been very helpful, as well.The content is great. I just wish I had known it had no linked index, and so many textual errors. I would have shopped around for a better version.
