July 19, 2018

Two of the world’s most comprehensive international law libraries, the Law Library of Congress and the Peace Palace Library based in The Hague, Netherlands, have agreed to form an information-sharing relationship to exchange information and better serve library users. A memorandum of understanding (MOU) was signed today in a ceremony at the Library of Congress by Law Librarian of Congress Jane Sánchez and Librarian of the Peace Palace Library Jeroen Vervliet.  The agreement Provides Valuable Insight into Services, Collections and Cataloging at Two Leading Law Libraries

Collaboration between Peace Palace Library and Law Library of Congress

“The Peace Palace Library is one of the world’s preeminent international law libraries, serving the International Court of Justice, the Permanent Court of Arbitration, The Hague Academy of International Law and other tribunals in The Hague,” Sanchez said. “It plays a central role in the network of international institutions in The Hague and in the international law community worldwide. Its collection includes more than 1 million volumes on public and private international law, foreign law, international relations and diplomacy. Learning more about the Peace Palace Library and how it develops and catalogs its collection will provide valuable insights.”

The Law Library of Congress will benefit from this collaboration in fulfilling its primary mission: providing foreign, comparative, international and U.S. law research and reference services to Congress, the federal courts, federal agencies and legal researchers, Sanchez said. “The Law Library of Congress is a truly global legal research institution,” said Vervliet. “Drawing on a legal collection covering every jurisdiction of the world, it performs comprehensive foreign, comparative, international and U.S. legal research for members of Congress and their staff, and also serves the federal judiciary and federal agencies. Learning more about how the Law Library of Congress supports the work of its governmental patrons and its other users, and about its unparalleled collection and how it is cataloged, will provide insights that can aid the Peace Palace Library. The Library serves institutions in the Peace Palace and The Hague, scholars and students of international law, and plays a leading role in international legal research and international law librarianship.”

Sharing information

Under the MOU, the Law Library of Congress and the Peace Palace Library will share information regarding their research and reference services. This can include research methods and techniques and how they are applied in responses for the various types of users each institution serves. Both libraries will also share information on the preparation of written reports and other research products and how they deliver research and reference services to their respective patrons.

Under the MOU, the parties may also share information about collection development. This can include information on collection development policies that are oriented toward particular user groups and how library staff create and employ the policies and keep them up to date. The MOU also provides that the Law Library of Congress and the Peace Palace Library can share information about cataloging, such as the system of classification and the subject headings that each has developed.
