Dear Nektarios, I am so sorry, I missed your question! My answer is, at my secondary school, we read a modern Russian translation of the "Slovo," with just a few quotes in the original Slavonic. Also, it was mentioned in our Ukrainian Literature class, and we read parts of a modern Ukrainian translation, as I recall. At my university (Kiev Medical Institute) there were no classes that would teach mediaeval Slavic literatures.
Galina-Volga, thank you so much for the link! Чи Ви часом нe українка? Приємно познайомитися!
