The Ranch El rancho question

I am curious what are the correct words to describe this sort of writing? I formatted the book with a Parallel text for learning Spanish or English. Translations are unique testaments and educational, the text builds vocabulary and makes for easy conversation.
These short stories have been told at parties and to strangers for forty years. The text crosses cultures and brings joy to anyone who is learning to bridge two worlds. From Spanish to English while parallel reading.
Do we say Parallel Reading, Parallel text Books, bilingual books, or bilingual books? thank you
