This is the full ebook (with text, not OCRed); it isn't scanned, but images are at screen resolution inside PDF.
I was trying to upload the actual scans I myself made of the physical textbook here, because when I scanned the textbook page by page, there was no ebook that I could find to purchase. This was one of my textbooks at college, you see.
Well, this was uploaded by someone on NitroFlare but required a premium account, so here it is for the world to enjoy for free :)
