The United Nations Convention on Contracts for the International Sale of Goods (CISG) came into force in 1980 and has been ratified and adopted by over 50 of the world's major trading nations.

This landmark Convention has set the tone for the harmonization of international law and by its widespread acceptance spurred progress in the harmonization of laws in other areas. Scholars and practitioners from around the world have written extensively on the development and impact of the CISG while courts and arbitral tribunals have issued opinions and judgements based on articles of the Convention.

Because of this growing body of information, a need arose for a reference work that would provide easy access to this subject. For the past 20 years Professor Michael Will has been recognized as compiling the most definitive bibliography of books and articles on the CISG as well as a comprehensive digest of all cases related to the CISG.

Now that the Convention for the International Sale of Goods is reaching its twentieth anniversary and the number of writings on the CISG exceeds 2,000 items and case law and arbitral decisions number over 200, the time is opportune to publish Professor Will's important reference work for wider dissemination.
