The Corts Foundation supports the Leiden University Office Tokyo (LUOT), where the Senshi Sosho project is conducted.

The Tokyo Office has translators and editors to work on the current volume 3 about the Japanese invasion of the Dutch East Indies.

For more information about the project, see: www.cortsfoundation.org/projects/senshi-sosho

The renewed website of LUOT is recently launched and will be developed further in future to publish results of the project.

The website can be reached at www.luot.jp


In late 2013 and the beginning of 2014 Maarten Manse, student at the Leiden University, and Hendrik Niemeijer, historian and project manager of the Corts Foundation, discovered more than 4300 transcribed and translated diplomatic letters in the VOC archives at ANRI, Jakarta Indonesia. These letters are hidden in the handwritings of the Daily Journals of Batavia Castle. This discovery led to a project plan to publish and provide access to these letters to the public and to researchers of the Dutch and Indonesian history in particular.

The letters were exchanged between the VOC's High Government in Batavia and sultans and rulers in the Indonesian Archipelago and other rulers in Southeast Asia (in particular Siam), between 1683 and 1743. These unique letters are kept in the VOC archive in Arsip Nasional Republik Indonesia (ANRI) in Jakarta.

Realization will take place on the Indonesian website Sejarah Nusantara (www.sejarah-nusantara.anri.go.id) with a searchable database of all identified letters, a geographical visualization of the reconstructed document flow between the over 200 different locations, and a few significant letters will be selected and published in the Harta Karun (Hidden Treasures) section of the website.


The project will be realized in six months from July until December 2014.

DutchCulture and the Dutch Embassy in Jakarta support this project and have assigned grants to help realize these objectives.

Also Leiden University supports the project and provides student Simon Kemper to assist in the realization.

A Prezi presentation was recently created to visualize all the different components of the Digital System at ANRI (DASA). This system is developed by ANRI and TCF together and is online at sejarah-nusantara.anri.go.id since September 2013. It will continue to be improved and extended for the next few years to come. 

The DASA system is not only a website, but it supports a publication process from scanning the old 17th and 18th century Dutch archives, storing the scans, adding metadata, adding indexes and search, and finally showing all on the web.

If you have any questions about this webbased publication system feel free to contact us at The Corts Foundation.
More information about the DASA project is also available on the project page.
