When delving into the topic, it is initially surprising that a significant number of libraries possess mummies and even display them in their reading rooms. Although it may seem otherwise at first glance, library mummies are more than just a mere curiosity or morbid adornment of venerable book collections. Eric W. Steinhauer demonstrates in the second volume of the series "Morbides Bücherwissen" that the mummies stored in libraries, both then and now, possess an astonishing media and visionary potential. Furthermore, the embalmed mummy in the library serves as a metaphor for permanence and immortality, which is also expected of libraries. The richly illustrated discussions are complemented by a comprehensive bibliography and an inventory of current and historical library mummies. The first volume of the series has already been published.
