On the right and left of the entrance, we see the names of the donors who have contributed to the creation of the library by donating money, books, furniture, housing, as well as material resources. Apart from Nikolopoulos and Kallianiotis, whose collections you will see on the upper floor, we find the names of Andritsanite surgeon P. Petropoulos. Founder of the Swiss Association of Friends of the Library, Petropoulos has been instrumental in maintaining and upgrading it. At the same time, there have been other important benefactors who, through their actions, contributed to the enrichment of the collections through donations, such as former director of D. Priggouris and his predecessor, Ag. Tselalis.
