THOUSANDS OF OLD BOOKS 



Have accumlated in the libraries of our public institutions, and those of prominent public men, 

 both in duplicate and otherwise. Thev cost them nothing and oft-times are valued accordingly. 

 They are. however, both valued and desired by specialists and parties interested. Perhaps you 

 or your friends may have some of the identical volumes which I desire, crowding library shelves 

 or stowed away in garrets, doing nobody any good; but had 1 thera I would not only appreciate 

 them but might know of a dozen others who would do likewise. Look over my list of wants and 

 if you have anvthing I desire or others write me, stating what you wish in exchange, and perhaps 

 we can arrange an exchange which will be advantageous to each. I will exchange for single vol- 

 umes—but the larger the exchange the better.
