This book by Ditmar Elyashevich Rosenthal includes two reference books: "A Guide to Punctuation." Edition 2 (p. 3-248) and "Management in Russian." Edition 3, revised and supplemented (p. 249-539). Punctuation reference. The current punctuation norms are based on the "Rules of Russian Spelling and Punctuation" (1956). These rules are in many ways imperfect, but they remain so far a single basis and, taking into account some corrections and clarifications made by practice, a guide to action.
