THE LIBRARY. 803 



sent witli a ojeatcr dop:ree of accuracy the actual use of the books, 

 the statistics of the loans have been kept in more detail since the 

 1st of January, 1912, the charges to indi^-iduals having been kept 

 separate from the charges to libraries. The sum total of the books 

 charged to individuals by the main Library and the bureau and 

 division and office libraries represents the number of books borrowed 

 for use by indi^'iduals; the remaining charges represent merely the 

 record of the books shifted from one branch of the Library to 

 another either for filing or to i\U the request of some reader. In the 

 latter case the record of its use by the mdividual is kept amon^ the 

 charges to individuals. In the following table giving the statistics 

 for the six months January to June, 1912, only the charges to indi- 

 viduals have been included, the charges to libraries (including the 

 main Librar}^ and the bureau and division libraries) having been 

 eliminated. The number of charges to indi\'iduals gives a more 

 accurate idea of the actual use of the books than it has been possible 

 to give in the past, but they can only be regarded as an approximate 

 statement by no means representing the full use of the Library.

As the use of the Library during the six months, July to December, 

 191 1, was probably about the same as during the six months elanuary 

 to June, 1912, the circulation of books to individuals for the whol 

 fiscal year may be given as approximatel}^ 51,000.
