Yisroel Mizrahi estimates his collection to be about 150,000 books, including Judaica books in English, Hebrew, Yiddish, German, Ladino, Persian, French and many other languages. (Resnick).

When he was asked about kind of books he sells he responded, “Basically anything the Nazis would’ve burned or killed the author” (Krausz).

His rule is that the book needs to have some sort of Jewish identity, not just be written by a Jew. This does not mean it has to be a biblical book. For example, he carries Shakespeare in Yiddish (Resnick).

While the store is full of rare gems, he also sells books for as little as $3 or $4.

His store also contains things other than books. In the bookstore window, he has a small can of shaving cream from the 1930s, along with a copy of the rabbinic ruling permitting men to shave.

He has pages of the Moroccan Rabbi Baba Sali’s handwriting, which are listed at $1,400.

Mizrahi pays attention not only to the books themselves, but also to the stamps of former owners, including inscriptions in books given as gifts and stamps of publishers or presses from far-flung places. These inscriptions and stamps are the markings of a map tracing back in history and they show how far these books and their ideas traveled.

He regularly finds books that are not recorded anywhere else (Ungar-Sargon).
