Russian Orthoepy. Resources.

Russian stresses can be maddening. There is hardly any pattern and they can shift depending on the grammatical form, the presence of a preposition which creates a liaison with the noun, or simply because of social and educational background of the speaker. Languagehat once mentioned the word коротко (short) that can have stresses on each of the o-s.

'Correct' stressing is highly valued among educated Russians, it's a sign of being 'one of us.'

Most ordinary dictionaries give stresses. And there is a number of print and online dictionaries and websites specifically dealing with standard and non-standard stresses and pronunciation.

Here is a short list.

Among the printed dictionaries one of the most authoritative is the Ageenko/Zarva Dictionary of Stresses for the Employees of Radio and Television (Агеенко Ф. Л., Зарва М. В. Словарь ударений для работников радио и телевидения / Под ред. К. И. Былинского. М., 1960; 6-е изд. испр. и доп. Под ред. Д. Э. Розенталя. М., 1985.). The 1960 edition is still used and there was an updated edition in 1985. This dictionary may be the biggest influence in instilling stress standards since it is used by radio and tv editors, announcers and presenters. I couldn't find it online.
