PREFACE. 



The Ixikhnational Catalocjue oe Sciextific Literature, com- 

 mencing with the literature of the year 1001, is an outgrowth of the 

 Catalngiie of Scientific Papers relating to the scientific literature of tlie 

 nineteenth century, published by the Roynl Society of London. 



The suggestion to catalogue scientific papers may be traced back 

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

 under the notice of the JBritish Association for the Advancement of 

 Science at its meeting in Glasgow, in I800. The history of the incep- 

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

 of Scientific Pcrpers issued by the Royal Society in 1867. Twelve 

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

 pabli.>^hed during the period 1800-1883 are arranged under authoi's' 

 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 18S4-1'J00 is now being prejjared by the Royal Society of 

 London. 



The possibility of preparing a complete index of current scientific 

 literature by international co-opei'ation was first taken into considera- 

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

 apparent that the work was bej^ond 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 

 I)}' international co-operation, steps were taken to sunmion an 

 International Conference of Delegates appointed by various 

 Governments. 



The Conference took place in Loudon on July 14-17, 18'J(*, 

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

 IVance, Germany, Greece, Hungary, Lidia, Italy, Japan, Mexico, 

 Natal, the Netherlands, Xew South Wales, New Zealand, Norway, 

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

 States
