General rules and general outline of the classification
History material is classified using the Dewey Decimal Classification system, 21st and 22nd editions
The classification pattern used within the historical collection (Dewey 9) is by country, period, subject
The EUI library introduced capital letters after the Dewey for a better definition of historical topics
Books are classified into the historical collection (9) when they are using historical methods. Many history books are also shelved within the political science and economic collections (Dewey 30 or 32 or 33) especially when they are dealing with the period after WWII
In addition to the main classification number used for the shelf placement of monographs and journals, supplementary Dewey classification numbers are frequently given
Example: our classification policy allows users to approach the stock of the collection from two -or more- starting points, different classification numbers:
A book called Japanese success? British failure? Comparisons in business performance since 1945 is shelved at 941.085-S which means: History, Great Britain, 1945-1999, Economic history.
The book is to be found first looking at the subject in its country/period framework which is also the shelf number of the book.
That same book has also a secondary Dewey number: 338.941009045 referring to "Industrial management and Industrial policy -- Japan -- Great Britain"
Using this second Dewey classification number, related books by subject can be identified, thus broadening your search
