The list of keywords is in English only. In order to make it easier to use, it is organized under headings in which the words or expressions are ordered alphabetically. When clicking on a keyword, it is automatically copied to the search window. Then you may choose the operator AND or OR.
As a result, you get the list of references from the REVES bibliographic database which answers your request, whether the terms of your search are in the author, title or keyword fields of the database.
