(d.) Wheu the Society does not reside in a fixed place, its 

 publications must be dealt with as stated in b. 



e.g., Verhandlungen der GeselLschaft deutscher Natur- 

 forscher und Aertzte, Leipzig, should be shortened 

 to :~ 



Verh. Ges. dt. Naturf. Leipzig-. 



36. On receipt of the above lists the Central Bureau will 

 prepare a list of the Journals (whether special or general), 

 together with the abbreviated titles which it proposes to use. 



Copies of these lists will be furnished to each of the Regional 

 Bureaus, as soon as possible, and the abbreviated titles 

 therein given must alone be used by the Regional Bureaus in 

 sending material for the Catalogue to the Central Bureau. 



37. A general list of journals indexed in the Catalogue, with the 

 abbreviations to be used as references, will be issued with the 

 first edition of the Catalogue. A supplement, giving the addi- 

 tions to this list, will be issued annually and a new edition 

 at the end of five years. 



38. For the preparation of these supplementary lists the Regional 

 Bureaus are requested to send before the first day of October in 

 each year a list of those journals which are not included in 

 previous lists, but which they then wish to include. 



B.— PREPARATION OF THE CATALOGUE. 



39. The arrangements for collecting the material to be sent to 

 the Central Bureau will be left entirely to the Regional Bureaus, 

 and will probably be very different in different countries, but the 

 number of entries in the Catalogue and the form in which the 

 material for the Catalogue is to be supplied will be decided by 

 the Central Bureau, subject to the control of the International 

 Council. The attention of the Regional Bureaus is therefore 

 drawn to the following regulations : — 



NuMBEK OF Entries. 



40. Each Paper to be catalogued will be entered at least once in 

 the Authors' and once iu the Subject Index. It is intended at 

 first to keep the total number of entries below 160,000, and they 

 are not to exceed 200,000 without the permission of the 

 International Convention. 



It IS estimated that 160,000 entries will allow an average of 

 one entry in the Authors' Catalogue and two in the Subject 

 Catalogue.
