The collection mainly contains correspondence of the association’s Central Committee in Krakow with its branches. The language of the letters and other documents (minutes, reports, bulletins) is primarily Polish; a substantial number of the records are in German, and a few are in Yiddish and Russian.
The topics include organizational matters of the association, the economic situation of the deaf-mutes, special education, and contacts with the Jewish deaf-mutes’ societies in other countries.
There is also a file from an earlier period of correspondence relating to the school, “Mesiyakh Ilomim,” for deaf-mute children in the Vilna province, 1912-1913.
