One of the flagship projects of the IILCC was the Digest of International Investment Jurisprudence. This online database provides a systematic collection of legal statements from decisions rendered in investment treaty arbitrations and supports scholars, students and practitioners in their work and studies. The Digest is available at www.investment-law-digest.com and is edited by the IILCC in cooperation with the University of Siegen. Its use is free of charge. Currently, the database features over 1000 statements made by investment tribunals which can be searched by case, topic or relevant article. It does not claim to be exhaustive. 

On the German Investment Treaty Disputes website, the IILCC documented ongoing as well as concluded investment disputes with a German involvement. This provides users with an overview of all proceedings initiated by German investors against foreign states or by foreign investors against the Federal Republic of Germany.
