Since the MPIWG was founded, it has a collection of rare books that has been growing steadily and is of great importance for the history of science. The collection focuses on publications on mathematics, mechanics, astronomy, botany, physics and medicine from the 16th, 17th and 18th centuries. The collection also includes old maps from the East Asian region. In addition to the digital copies of our rare book collection, we also show some collections from institutes with which we cooperated in various projects and who have kindly given us permission to publish their works digitally. All works are available to you for free reuse (public domain).
