SYSTEM OF CLASSIFICATION AND AERANGEMENT OF 

 THE SUBJECT INDEX OF MODEEN WOEKS IN THE 

 BEITISH MUSEUM, 1881-1910. 



The Subject Index is not a mere Ust of the titles of books : it 

 is an index of the main subject or subjects of each work. 



Many books require only a single entry, but when more than 

 one subject is treated of, a book is entered under as many different 

 headings as are necessary. 



Classificatioji of Headings and Sub-headings. 



Under each country sub-headings will be found for works on 

 the following subjects : — Antiquities, Army, Colonies, Constitution 

 and Government, History (secular and ecclesiastical), Law (general 

 systems and codes). Navy, Politics, Population and Ethnology, 

 Social Life, Topography, Trade and Finance.
