The Augusta Library was born from the donation by the humanist and bibliophile Prospero Podiani of his book collection consisting of about 10,000 volumes. The donation act is dated December 22, 1582 and this date marks in fact the official birth document of the Augusta Library, which is therefore considered to be one of the oldest public libraries in Italy. The denomination adopted is explained by the humanistic use of the classic antiquity, and with the relationships that in the eighteenth century broke between the public library and the Augusta Academy. The constitution of the Library is a library designed and prepared, as a collection of books intended for public use by private initiative, Perugino Prospero Podiani, whose tenacious purpose of providing the city of a public library was supported by the availability of the library 'municipal administration. In 1623, the Augusta Library had a new home, where it would remain for more than two and a half centuries: the Meniconi Palace in Piazza del Sopramuro, opposite the University. Here, the library began to serve the public regularly, and 1623 is the year officially designated as the beginning of the institute's activity, as an epigraph kept in its current headquarters. At the end of the 17th century - librarian Giulio Cesare Barigiani - were made by the painter Giuseppe Scacioppa 60 portraits of illustrious Perugines to be devoted to 'ornament' of the library. During the 18th century, the Augusta Library became more and more the Institute for Conservation and Culture of the City, even though the economic resources were very limited, linked to non-profitable fixed income. In 1787, Dr. Luigi Canali, Felice Santi and Francesco Cerboni wrote the Scan Scanners Index, an indispensable tool for finding the library owner. After Giovanni Angelo Cocchi, a librarian who was politically engaged in republican movements at the end of the 19th century, began with the librarian Luigi Canali, tied to the environments of restoration, which despite having other assignments as a physics and chemistry professor at the University and as a member of the Provisional Pontifical Administration, carried out his task perfectly. He provided the library of an Index of Alphabet and Subject volumes and identified and classified distinct series of incunabula, aldine, and Perugine editions. With Adamo Rossi since 1857, the library had a true librarian for culture, by competence, for the passion of his work. Among the most important acquisitions during his direction was in 1867 manuscripts left by Annibale Mariotti,
