 metal lying idle year after year would of itself entail 

 great trouble and expense. The plates would take up 

 a great deal of room and would need to be kept in a 

 fire-proof building ; and the interest lost each year on 

 the value of the metal would by and by amount to a 

 formidable sum. It is perhaps doubtful whether, in 

 the long run, anything would be saved by this cum- 

 brous method. Possibly unless some future helio- 

 graphic invention should turn to our profit the least 

 expensive way, after all, may be to print at long 

 intervals, without stereotyping, and to depend 

 throughout the intervals on card-supplements. But 

 this question, like many others suggested by the 

 formidable modern growth of literature, is easier to

In this hasty sketch many points connected with a 

 librarian's work remain unmentioned. But in a brief
