We actually don't need the entire book in PDF or JPG form, just a digital image of the particular page or pages you referred to. You can have the digital image taken in an Internet shop, or you can simply shoot the pages with a mobile phone that has a built-in camera and convert the images to the desired format. This done, you can do either of two things: simply e-mail the image file to me so I can post it, or, if you know how, upload it to PhotoBucket or a similar image-hosting service and make your posting on the Forum to indicate the link. It's actually a very simple procedure once learned and done once.
I'm sure we can have a very lively discussion about that Wikipedia textbook citation once the Forum members are able to see that digital image.
