Abstract
Scientific work in medical informatics has been going on for more than 25 years; the results of this work are published in one way or another. How are these publications used to avoid the invention of the wheel for the second and third time? To get an overview of this, four proceedings of the Medical Informatics Europe conferences out of the last eight years have been analysed, to show the behaviour of authors in different countries and in different years in respect of citations.
