New to learning online here? This page explains how to use the TorahSages library and decodes the abbreviations you will meet along the way.
Every text opens in a clean, right-to-left reader. Use the A− / A+ controls to set the Hebrew font size — your choice is remembered on your device. Move between chapters or dapim with the previous / next links, and use the breadcrumb at the top to jump back to a book, tractate, or the Library.
On the Chumash, each verse can be read alongside Rashi, Ramban, Ibn Ezra and Sforno. On the Talmud, every daf carries Rashi and Tosafot. Use the toggles at the top of the reader to show or hide a commentary.
Beneath each siman you’ll find the Nosei Keilim — the classic commentaries printed around the text in the standard editions (Magen Avraham, Taz, Shach, Beit Yosef and the rest) — together with later commentaries such as the Mishnah Berurah, grouped by commentary author. After each se’if in the main text, small buttons show which commentaries discuss that se’if — click on a button to jump straight down to the note. A short legend on the page explains what each abbreviation stands for.
Use the search box in the header to look across sages, texts and shiurim. Browse the Library by category (Tanach, Mishnah & Talmud, Halacha, Jewish Thought, Musar), and the Sages by era — from the Shoftim and Neviim through the Tannaim, Amoraim, Rishonim and Acharonim.
The ראשי תבות table above expands the common acronyms for the Sages (for example רש״י, רמב״ם, רמב״ן) — each links to that sage’s page.
