Why Do YOU Need a 



General Reference Book? 



I 



No matter how narrow your special interests in science 

 are, and 



no matter how thoroughly you believe that this is an age 

 of specialization, 



no matter how much you may live up to that belief, 



still you can not afford to be penalized by that specialty 



to the extent of being ignorant of other fields of science, of 



letters, of art, of history and of politics. 



No matter how thoroughly "you know everything about 

 some one thing," 



still you want to know " something about every other 

 thing — or about a good many other things." 



It is only the comic supplement college professor or scientist 

 who knows psychology but takes no interest in the single tax, 

 or is so much an expert on wireless telegraphy that he cares 

 nothing about tariff or world trade, or confines himself to 

 artificial reproduction and wishes to know nothing about the 

 referendum or the problem of minority representation. 



You are a scientist with specialized interests, but you are 

 none the less — in fairness to yourself, your family, your 

 fellows, you can not help being — a citizen of the universe 

 and of your state and city or town with universal and general 

 interests. 



It is not probable, let us say, that you would count 

 yourself any more truly or merely a specialist than the men 

 whose names are printed on the margins of these two pages. 



In your special field of science, as they each in theirs, you 

 can know largely at first hand — by experiment and research 

 and not from books. But you have not the resources of 

 time or strength to get the same first-hand command of 

 information in one or more other branches of knowledge. 



A general reference book is your short-cut to this other 

 information that you can not get for yourself in the way that 

 you get information in your chosen field of science.
