Hello Jana. The book actually gives good descriptions of the statistics that are discussed, so I don't think it'll be too much of a problem. It is sort of a textbook that I had to read for my criminal justice course, and I found it interesting. Anyway, thank you all for your input! Have a great 4th of July! Scott Original message: Hi, all! Yes, and if a sighted person or someone who has access to descriptions of the diagram is validating the book, it might be helpful to include a description of the diagram which would normally be there. I would think that this would be particularly helpful when reading textbooks.
