THE INTERNATIONAL CATALOGUE OF SCI- 

 ENTIFIC LITERATURE.— SECOND 

 CONFERENCE. 



In Sciexce for August 6, 1897 I gave an 

 account of the steps which led to the hold- 

 ing of the first Conference on an Interna- 

 tional Conference of Scientific Literature, 

 and a somewhat detailed description of the 

 Proceedings of the Conference.* At the 

 invitation of the editor of Science, I shall 

 describe below the work done since that 

 time to reach a working plan for this most 

 important undertaking. 



The first Conference, in July, 1896, had 

 reached certain definite conclusions, which 

 may be brieflj' stated as follows : (a) That 

 it was desirable to publish a catalogue of 

 scientific literature by means of some inter- 

 national organization ; (i) that the cata- 

 logue was to be primarily for the scientific 

 investigator ; (c) that papers were to be 

 indexed according to subject-matter ; (d) 

 that the catalogue should comprise all pub- 

 lished original contributions to science ;(e) 

 that the catalogue be issued in the double 

 form of slips and books. 



The Conference passed a resolution to the 

 effect "that the Royal Society be requested 

 to form a committee to stud j' all questions re- 

 lating to the Catalogue referred to it by the 

 Conference, or remaining undecided at the 

 close of the present sittings of the Confer- 



* The article was also published in separate form.
