Three out of give for the content. Thorough, but pretty dull treatment of Greyhawk. Adventure hooks are lacklustre. I know 2E books of this era weren't exactly crackling with originality and inspiration, so this book about met my modest expectations.
One out of five for the scan. Several of the pages are missing content from being cut off, including the excellent regional map (the main reason I bought this PDF), rendering it largely useless. For the rest of the book, images bleed through onto the already muddy text. Cannot recommend.
