DIEECTIONS. 



The present volume contains a supplementary list of the periodicals 

 that are examined by the Regional Bureaus engaged in the preparation 

 of the index slips used in the volumes of the International Cata- 

 logue of Scientific Literature. 



It consists of the complete list of Austrian periodicals, and of 

 additions to the lists for other countries which were published in the 

 List of Journals issued in 1903. 



The list prepared by each Regional Bureau is divided into three 

 cohmms. The first column contains the abbreviation used in the 

 Catalogue to represent the periodical. The second column contains the 

 full title of the journal and its place of pubhcation. The third column 

 contains a number. These numbers are usually consecutive, and are 

 referred to in the short lists given at the end of each volume of the 

 Catalogue. 



In respect of each periodical, the last entry in the second column is 

 one or more of the letters A to R. These letters denote the sciences 

 under which it is thought that scientific papers occurring in the 

 periodical are likely to be catalogued. AVhere the indication is [A — R] 

 it is to be understood that papers belonging to all branches of science 

 may be looked for in the periodical to the title of which these letters 

 are attached.
