International insolvency law can be found on national, European and international level. Under the guidance of Yves Brulard, a group of authors have written two volumes on international insolvency law (in French). The first volume deals with the Insolvency Regulation (Recast), which shall apply from 26 June 2017. The second volume deals with national rules on international insolvency law, in a selected number of jurisdictions. The books can be ordered here, and are highly recommended.
