Balaban then won a high ministry scholarship, and departed for a long scientific trip to Poznań, Berlin and Gdańsk.

The next three years, he spent in Lublin as a referent (reporter) on Jewish matters by the Austrian General Government.

Together with Ozjasz Thon and Dr. Moses Schorr, Balaban was one of the founders of the Institute of Jewish Sciences in Warsaw.

Among his works the most important ones are: He wrote also a detailed article about the Vaad of four lands for the 11th volume of "History of Jewish people".

He published hundreds of articles which are devoted to the researches of rabbis', scholars', community leaders' activities as well as the history of bloody pogroms, about the Karaims in Poland and other topics.

Balaban's researches written in Hebrew on the history of movements of Shabatai Zwi and Jakob Frank are especially important to note.

The first more essential essays appeared in the almanac "Rocznik Żydowske" in 1902-1906: Some of these articles became the preparation for the mentioned already Balaban's work entitled "Żydzi Lwowscy na przelomie XVI i XVII wieku" (Jews of Lvov in the break of the 16th and 17th centuries, 1906, 577 pages of the text and 188 pages of the materials).
