In 1984, the year of the university’s 400th anniversary, the Main Library was relocated to the newly restored and modified building designed by Ricardo Magdalena (an architect and designer native to Zaragoza) that had been built to house the Colleges of Medicine and Science. In 2011, the Main Library, its associated services, and the European Documentation Center returned to the main hall. The old reading room now serves as an exhibition space for the BUZ collection.
