By happy coincidence I just happen to be reading this book by Richard Hollis. Jay from Things To look At had recommended it on NDG a couple of weeks ago when Ben had asked what basic typographic advice you'd give to students.
Even though I'd already bought it and it was waiting in the To Be Read pile, I thought it might have been too niche in that context. Now I'm half way through it I realise I couldn't have been more wrong. I can't think of any other graphic style/movement that was/is so inclusive. From the Arts and right through all levels of industry the Swiss style works, with dynamism, sensitivity and a super cool but still accessible sense of style - with clarity, purpose and economy at it's heart.
I don't know what other reviews are out there but, to me at least, I get the impression that Hollis ready knows his stuff, taking an extremely useful analytical approach at times.
The cut a long story short, Jay was damn right. This book should be essential reading.
With a predominence of Akzidenz Grotesk, Helvetica's forerunner, the book is lavishly illustrated with graphic design classics as well as more obscure examples you'll struggle to find anywhere else.
The only thing I find disappointing about the book is the rather uninspired cover but as soon as you open it that's forgotten.
