War marked an ending to the library's progressive period: the author Volter Kilpi, who started as a librarian in the Turku City Library in 1919, found the library in a state of degradation. During Kilpi's management the library slowly began to recover, but after a few years Kilpi left his post to start working at the recently established Turku University Library. The Turku City Library was a pioneer in patron counselling. Already in 1933 the library established a special help desk for the patrons, which was inspired by a similar service at the Stockholm Public Library. There had been a reading room for newspapers in the old People's Library since the year 1878, and during the 20th century the newspaper and magazine services were further developed and expanded. Already in 1907 a separate reading room for newspapers was established by Sofiankatu, and later on even more reading rooms for newspapers were established.

The library network expanded slowly when new branch libraries were established in different parts of the city. Turku also had the first mobile library in Finland, which started operating in 1961. The music library was opened on the first floor of the Main Library in 1970. The new main library (1971–) In the course of the 20th century the Main Library was getting too small and impractical for the demands of the quickly developing library services. For this reason many of the departments of the Main Library had to be distributed in different locations. Already in the beginning of the 1970s the music department was moved to the former residence of the provincial governor by Läntinen Rantakatu.
