Title
Subject indexing and authority control in archives : the need for subject indexing in archives and for an indexing policy using controlled language
Source
Journal of the Society of Archivists. 17(1996) no.1, S.27-54
Year

Abstract
Describes an experiment carried out in the City Archives of Oporto, Portugal to test the relative value for information retrieval of controling or not controlling vocabulary in subject indexing. A comparison was made of the results obtained by searching 2 databases covering the same archival documents, one of them without any control in the indexing language and the other with authority control. Results indicate that the database where authority control in subject indexing was used showed better performance and efficiency in information retrieval than the database which used an uncontrolled subject indexing language. A significant complementarity between the databases was found, the addition of the retrievals of one database to those of the other adding considerable advantage. Posits the possibility of creating an archival authority list suitable for use in groups with identical characteristics, such as local archives of judicial groups. Such a list should include broader terms, representing subject classes, which will be subdivided into narrower terms, according to the particular needs of each archives or archival groups
