In 1940
The New York Sun newspaper issued an elaborate, expensively produced hard-cover book entitled
Valuable Data of New York, the World's Greatest Market presenting a very comprehensive analysis of its readership directed at advertisers of a very wide range of products. The 1940 volume described itself as
The Sun's 17th annual "data book". The care and expense to which
The Sun obviously went in the compilation of data and its presentation in this volume reflected its importance to the newspaper. The high cost spent on the volume with its fancy binding, numerous inserts, and many die-cut tabs on both the outer edge and the top edge of the book, reflected the richness of the advertising market in the era when print advertising predominated.
