I received a marvelous email from Zakir Hossain, Teacher-Librarian & Extended Essay Coordinator at the European International School in Ho Chi Minh City. He provided me with the two translations for these signs. These are not quite like the other double-translation posts: their difference is in the words themselves. It’s not school and public library; it’s basically synonyms for the word library. At least that’s how I understand it (please correct me if I’m wrong).
Thank you for both of these translations Zakir!!!
লাইব্রেরি = English pronunciation of Library
