If you know anything about design, the words Paul Rand retain some meaning for you. It may be vague, perhaps one of your professors recommended you look him up, maybe one of your design icons listed him as an influence.
Or quite likely you have seen some of his work, and never knew the man behind such world famous, global dominating logos. This has to be the most in depth Paul Rand book I have read, and I have borrowed many from various libraries. Which inclines me to say that if the history of design has ever intrigued you or you just like Mr.Rands work, then this is probably the best choice for you. Not only does it have a ton of images but it's probably the best bang for you buck as far as Rand books go.
This is a pretty thorough book on a graphic design icon. Unfortunately, the book is typeset very poorly in an 8pt serif font. Reading more than a few pages at a time strains your eyes and results in a headache - ironic considering Rand was a firm believer in usable design.
Lots of full color samples of Rand's work to coincide with the text, which is nice.
Overall, this book is a great resource. It's too bad the type is so difficult to read.
Paul Rand was one of the 20th century's most important graphic designers and Steven Heller's book is a marvelously informative survey of the work of a man whose diverse work set a standard for excellence in graphic design
