Suppose I'm working with a language that doesn't have much data available; the largest corpus around is a translation of the Bible, which is free to read online, but is presumably still copyrighted by the translator. Or suppose I've found a corpus of books to scan in, but those books were recently published and thus still under copyright.
What can I do with that corpus, by law and by academic convention? For example, if it's freely available for reading (or if I've purchased a copy), does that also mean "freely available for running a statistical analysis on"? Can the results of that statistical analysis be redistributed, even if the original text can't?
I'm not sure if there's much legal precedent in this area, but I'm sure there's quite a lot of academic precedent in linguistics—corpora have to come from somewhere, after all.
EDIT: I'm asking this question from America, but information from anywhere would be useful!
