REPOET 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 Liter^ature 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 J^ear, 

 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 

 IG 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 : 



Pages. 



First annual issue 7,763 



Second annual issue 8,826 



Third annual issue 8,493 



Fourth annual issue ■.■ 8,681 



Fifth annual issue ^ 10,785 



Sixth annual issue 10. 049 



Seventh annual issue 9, 219 



Eighth annual issue _> 8,699 



Ninth annual issue 7,933 



Tenth annual issue 8,447 



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
