Hi
Some languages - particularly Lithuanian - use "Sentence case" for book titles. I.e. first letter of the book title is Uppercase, rest of the words are in lower case (if words are not referring to names or places). If title consists of two sentences then again Uppercase letter at the beginning of next sentence.
But problem is that all titles downloaded by Goodreads plugin are converted to Title case. This should be optional. Please see example of Lithuanian book in Goodreads:
"Mirtis šampano taurėje"

And how it is downloaded
