Goldstein raised his daughter's son, Abraham Sternhartz, after the latter was orphaned of his parents as a young child.
These formed the basis for his definitive collection of Breslov oral traditions, entitled Tovot Zichronot.
Goldstein was the first to write a learned commentary specifically on Rebbe Nachman's teachings, giving scholarly legitimacy to the Breslov movement after the death of Reb Noson in 1844.
Many of today's English-language translations of Breslover works were only made possible because of the Tcheriner Rav's meticulous research and elucidation.
The ones that survive are: Goldstein also produced a collection of source texts for Sefer HaMiddot (The Aleph-Bet Book—a collection of aphorisms on character traits), tracing Rebbe Nachman's references throughout the Bible, Talmud and Midrash.
