Testimonials
“The IMB was one of the first bibliographical research tools I used as a graduate student at the University of Toronto in the 1980s. Then in book form, it instantly became an indispensable tool for all my graduate research. With its digitisation in the 1990s, the IMB turned into an even more valuable resource with its extensive and comprehensive searches. Indeed, whenever I begin a new project, I begin it with an IMB search. As a graduate supervisor for more than 30 years at the University of Bristol and now at the University of Calgary, I have recommended the same approach to dozens of PhD and MA students. May the IMB long continue to support emerging and established scholars on their journey to (re)discover the past.”
Carolyn Muessig, Chair of Christian Thought (University of Calgary)
“The IMB has been a fixture in the lives of many medievalists since the days when it was a printed book. Now, on the internet, it is an even more useful and easy-to-use resource. The study of the Middle Ages covers a wide chronology and geography, and is inherently interdisciplinary, with most scholars needing to keep up with developments in several adjacent disciplines. The IMB is the only bibliographical resource that meets this need, enabling all medievalists to track down the research most relevant to their work from across a wide range of publications.”
Professor Judith Jesch (University of Nottingham)
“Whenever one contemplates starting some scholarly work on a medieval topic, it is sensible to find out what has already been written about that topic over the last decades. I always start by searching the International Medieval Bibliography. It is simply the best international bibliography on the Middle Ages, and, irrespective of discipline, topic, area, or era, it never fails to come up with helpful references to literature. Of course, you never find all the references you need in the IMB – but then, you would not find all of them in other bibliographies either. And there is more: the references you do find in the IMB may help you set up lines of enquiry you had not thought of before. The time spent consulting this online bibliography is time well spent, as the IMB really can help your research along.”
Professor Marco Mostert (Utrecht University)
