Unfortunately, the PDF version is a scanned image of the textbook pages, so the text cannot be cut and pasted into this wikibook directly. However, Google automatically generates html versions of documents as it crawls the web. Therefore, if you perform a Google search for the PDF file, you will frequently (but not always) find a link to an poorly formatted HTML version that was created using optical character recognition (OCR) software.
An easy way to work on this chapter is to cut and paste the text from the HTML version, and then capture the images from the original PDF version. Otherwise, you may have to retype the text from scratch (ugh).
