Finding books in Arabic and Persian
Items in Arabic can be found by typing in Arabic or Roman script.
In January 2015 Leiden University Libraries started cataloguing Arabic and Persian book titles in Arabic script, following items catalogued after this date can be found by using Arabic script.
Also from 2015 Leiden University Libraries started ULL use romanization tables that were approved by the American Library Association and Library of Congress (ALA-LC) for the transliteration of records from Arabic into Roman script. ALA-LC is widely used by many libraries around the world, and is therefore increasingly seen as the new international romanization standard.
Prior to 2015 a Dutch nationally approved romanization was in use. Old titles have not been transferred to the new system. Thus, when searching the catalogue keep in mind to search using both the old romanization (to find everything that was catalogued before 2015) and either the arabic script or the ALA-LC romanization (to find everything that was catalogued after 2015).
Unfortunately, other languages using Arabic script, such as Persian, are not catalogued in Arabic. However, these languages are transliterated according ALA-LC.
