I'll say it bluntly then - I know nothing, zip, zilch, about copyright law.
But anyway, I am one of the probably dozens of people here on this forum using New Penguin Russian Course as an indispensable resource. Would it really be so lawless if some Russian speakers (or, I suppose, foreign speakers of the Russian with decent accent) recorded themselves reading the dialogues and texts of this excellent book for us on this forum to listen? The basic of language is sound, and the Penguin course seems excellent, but unfortunately it doesn't seem logical that I should complete a whole Russian course without having listened to any of it. (of course, though, there are plenty of places online and several courses that utilize sound). I hope only for sincere responses - as I have said, I really know nothing about copyright law and am just asking a question (though, I think perhaps it's worth nothing that there are a couple texts in the book that are adapted from other texts, or are short stories, such as the ones near the end by Chekhov).
I apologize for seeming ignorant. I also apologize if i have made some mistake, my English is a bit erratic after midnight or so.
