The Samos Library Branch has been operating since 1987, i.e. when the Department of Mathematics was established. It is located in Karlovasi, and is housed in a restored neoclassical building constructed in 1903, the Hatzigiannio Girls School. The Hatzigiannio Girls School was constructed in the place of the former Porfyriada School and the Agia Sophia Church. Its construction was funded by industrialist and politician of the Samian State Giannis Hatzigiannis to house the Girls School that had been operating in Karlovasi since 1861. Founded in 1902, the Girls School was completed in 1905 and was named Hatzigiannio after its benefactor Hatzigiannis. It served as a school building throughout the years, except for the Greek Civil War period (1945-1949). In 1989, it was bestowed to the University by the Municipality of Karlovasi. The building was renovated according to plans drawn up by the architect of the University of the Aegean, Mr. K. Lapathakis, and started being used as the Department Library branch.
The Branch Building covers an area of approximately 920 sq.m. and includes two levels.
