A large part of our collection is searchable through the Peace Palace Library’s online catalogue. This catalogue is unique, because it classifies not only books and (journal) articles according to their subject, but also book items.
In its classification of all books, book items, journal articles and other types of publications, the Library tries to remain faithful, as much as possible, to the famous Catalogue de la bibliothèque du Palais de la paix, designed in 1916 by Elsa Oppenheim, daughter of the renowned international lawyer Jacques Oppenheim.
At the same time, the Library also uses a more modern classification system, which consists of around 5,000 keywords. In order to help visitors make the most of these classification systems, the staff of the library offers a monthly Peace Palace Library Introduction Course.
In short, there are several ways to search in our catalogue for a book, article or journal from our library.
- Searching by keyword:
Almost all books, articles and documents in our library have been given one or more keywords. Search our library's keyword index if you are looking for materials in a specific field, geographic region, certain cases, or treaties and conventions. Please choose 'subject headings' from the dropdown menu with the search indexes used in our catalogue system
- Searching known author:
If you know the author of a book or article, the easiest way is to search our catalogue directly through the library's authors index. Please choose 'author' from the dropdown menu with the search indexes.
- Searching known title:
If you are looking for a specific book of which you know the title, the easiest way is to search our catalogue directly through the library's titles index. Please choose 'title words' from the dropdown menu with the search indexes.
- Searching all words:
If you want to do a search on certain words, either in the title or somewhere else, the easiest way is to search our catalogue directly through the library's all words index. Please choose 'all words' from the dropdown menu with the search indexes. You can try searching by all words here:
Plinklet is the library's own link resolver. In all shown records in our catalogue, you can use plinklet to show you various extra options to access the article (paper or electronic), and it will give you various suggestions for further research, such as relevant keywords, recommended articles and books, et cetera. To get to the plinklet page, all you have to do is click the plinklet icon.
