This book contains a wide range of old fashioned line-art, nothing spectacularly different from stuff already on most designer's bookshelves, but this publication comes with a cd (mac and pc compatible) that contains all the images , scanned, properly cleaned up and saved at a reasonable resolution as bitmaps. This makes them ideal for including in page layout applications, and means you can colour them and place over other images without resorting to clipping paths. Limited in scope, but well worth the price even if it saves you having to do one scan for one project.
