Despite having only ninety-six pages and using a grid that uses about three-quarters of each page (and not forgetting the text in a large point size) this can be a useful book for a designer new to publication grids. Hurlburt was a great Art Director who elevated the every two weeks Look magazine into a must-see for designers. His books always looked beautifully designed but I always thought they were rather lightweight in content -- like this grid book.
The contents look at the use of grids in newspapers, magazines and books but there really aren't too many examples shown and nowhere is there a page or spread from a publication with a grid laid on top to show exactly how the grid helps create the page design. On page fifty-eight there is a whole page illustration of a grid for the German magazine 'twen' which would be much more informative if it was laid over an actual 'twen' page showing how the headlines, columns of type and pictures conform to the grid. It's slightly annoying that most of the grids in the book are in sort of muddy mid-brown panels with black lines for the columns.
Hurlburts book is lovely to look at but there is no comparison with Grid systems by Muller-Brockmann.
BUYER BEWARE NOTE I bought a paperback copy of this book recently but it was a print-on-demand inkjet copy which I thought was very poor because it's black only so that the mid-brown second colour in the original hardback is reproduced as grey. The reproductions in the original were not that good to start with and made worse in the inkjet copy. I think it's worth looking around the net for the original hardback copies from Van Nostrand (1978) or this copy from Barrie & Jenkins (1979). My inkjet reproduction copy is of a Wiley paperback published in 1982.
