PREFACE. 



The International Catalogue of Scientific Literature, com- 

 mencing- with the literature of the year 1901, is an outgrowth of the 

 Catalogue of Scientific Papers relating- to ihe scientific literature of the 

 nineteenth century, published by the Ro}al Society of London. 



The suggestion to catalogue scientific papers may be traced back 

 to Prof. Henry, of Washington, U.S.A., who brought the subject 

 under the notice of the British Association for the Advancement of 

 Science at its meeting in Glasgow, hi 1855. The history of the incep- 

 tion of the enterprise is recorded in the first volume of the Catalogue 

 of Scientific Papers issued by the Royal Sociely in 1867. Twelve 

 large quarto volumes have been printed in which the titles of papers 

 published during the period 1800-1883 are arranged under authors' 

 names. A subject index, which will serve as a key to these volumes 

 and also form an independent record, is in an advanced state of 

 preparation. A catalogue of the scientific papers published during the 

 period 1884-1900 is now being prepared by the Royal Society of 

 London. 



The possibility of preparing a complete index of current scientific 

 literature by international co-operation was fii'st taken into considera- 

 tion by the Royal Society about the year 1893. It had long been 

 apparent that the work was beyond the resources of the Society, or 

 indeed of any single body. Moreover, it was felt that an authors' 

 catalogue could not supply the required information, and that it was 

 essential that scientific workers should be kept fully and quickly 

 informed of all new discoveries by means of complete subject indexes. 

 International co-operation appeared to be the onl}' means of carrying 

 out such a work with the necessary completeness and rapidity. The 

 Society therefore sought the opinion of a ver}^ large number of 

 representative bodies and individuals abroad ; and, as the replies 

 were almost uniformly in favour of the work being undertaken 

 by international co-operation, steps were taken to summon an 

 International Conference of Delegates appointed by various 

 Governments. 



The Conference took place in London on Jul};- 14-17, 1896, 

 and was attended by delegates from Canada, Cape Colony, Denmark, 

 France, Germany, Greece, Hungaiy, India, Italy, Japan, Mexico, 

 Natal, the Netherlands, New South Wales, New Zealand, Norwa}"-, 

 Queensland, Sweden, Switzerland, the United Kingdom, and the Ignited 

 States.
