Why Edison Succeeded 



You can't get on in the world unless you read 

 — read the books which will make you more 

 valuable to those for whom you work. You 

 don't have to go to college. Edison never went 

 to college. But he has probably the finest 

 library of technical books in this country. 



If you want helpful, practical books on 

 electricity, mechanics, mechanical engineering, 

 wireless, airplanes, sheet metal work, repairing, 

 write to the Popular Science Monthly's Readers' 

 Service Bureau. Tell us in what subjects you 

 are interested and we will compile a list of 

 books, with their prices. 



We will send more than a mere price list. 

 We will select out of a hundred or more titles 

 the very book which, in our opinion, meets 

 your requirements. 



Whenever you are at a loss for an inexpensive, 

 practical book, or for information about books, 

 write to
