REPORT ON THE INTERNATIONAL CATALOGUE OF SCIENTIFIC 
LITERATURE. 
Sir: I have the honor to submit the following report on the operations of 
the United States Bureau of the International Catalogue of Scientific Literature 
for the year ending June 30, 1911, together with a report of the proceedings 
at the Second International Convention of the International Catalogue of 
Scientific Literature held in London July 12 and 13, 1910, outlining the general 
condition of the whole enterprise: 
The appropriation made by Congress for the maintenance of the bureau 
during the year was $7,500, an increase of $1,500 over the appropriation for 
the previous year. 
Five persons are regularly employed in the bureau, and the services of 
temporary clerical assistants occasionally engaged. 
In order to properly analyze and classify the many scientific works now 
being published in the United States it is not only desirable but necessary to 
obtain the advice and assistance of scientific men who are specialists in the 
several sciences included in the scope of the catalogue, and the increase of 
$1,500 in the appropriation for the catalogue this year has made it possible to 
have some of the more technical papers referred to such specialists. 
It is a matter of gratification to report that the utmost interest has been 
shown by all the scientific men who have been approached for aid, and that for 
a nominal sum classification citations are prepared and furnished to the bureau, 
thus rendering it possible for the scientific publications of the United States 
to be not only indexed in a thorough bibliographical manner, but also, when 
necessary, Classified by specialists. The classification numbers used in the 
subject-catalogue refer to the subject-contents of the papers cited, and furnish 
the equivalent of an abstract of each paper indexed. 
During the year 26,020 cards were sent from this bureau, as follows:

Thirty-two regional bureaus are now cooperating in the preparation and 
publication of the International Catalogue of Scientific Literature. The cata- 
logue consists of 17 annual volumes published by a central bureau in London. 
The regional bureaus are maintained by the countries they represent, usually
