Is there a word for side-by-side translations?
Solution 1:
I believe that the word you're looking for is parallel translation.
Solution 2:
Another term, polyglot edition, refers to books published in a form where the original language is printed on left-hand pages, the translated text on right-hand facing pages. You can view a sample of such a text here.
Solution 3:
A word-for-word translation under the original text is known as an interlinear translation.
