APPENDIX 1. 
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 Cata- 
logue of Scientific Literature for the year ending June 30, 1914: 
This enterprise was organized in 1901 and has for its object the 
preparation and publication of an annual classified index to the 
current literature of science. The catalogue is published in the 
form of a classified book index, each paper referred to being first 
listed under the author’s name and again under the subject or sub- 
jects of the contents. Seventeen main volumes are issued each year, 
one for each of the following-named branches of science: Mathematics, 
mechanics, physics, chemistry, astronomy, meteorology, mineralogy, 
geology, geography, paleontology, general biology, botany, zoology, 
anatomy, anthropology, physiology, and bacteriology. 
All of the first 9 annual issues have been published, together with 
16 volumes of the tenth issue, 8 volumes of the eleventh issue, and 
1 volume of the twelfth, a total of 178 regular volumes, in addition 
to several special volumes of schedules, lists of journals, etc. The 
number of pages in each annual issue is shown in the following 
table:

The large increase in size of the fifth and sixth annual issues 
necessitated a change in the plan of publication, the object in view 
being to reduce the bulk and consequent cost of the work while not 
reducing its usefulness. This has been accomplished by printing 
the full titles and references only once—that is, in the author cata- 
logue—the subject catalogue containing only the author’s name and
