The International Medieval Bibliography (IMB) was founded in 1967 with the support of the Medieval Academy of America, with the aim of providing a comprehensive, current bibliography of articles in journals and miscellany volumes (conference proceedings, essay collections or Festschriften) worldwide. Its editorial staff is based at the Institute for Medieval Studies at the University of Leeds, and the project is supported by over 50 teams of contributors in Europe, North America, Australia and Japan.
The IMB shares an interface with the Bibliographie de civilisation médiévale and the International Bibliography of Humanism and the Renaissance.
Together, they make up the cluster Brepolis Medieval and Early Modern Bibliographies.
