To create a Harvard reference for the textbook "Pathways Across Cultures", you would typically format it like this:
Author(s) Last Name, Initial(s). (Year) Title of the Book. Edition (if applicable). Place of publication: Publisher.
However, since I do not have access to the specific details of the textbook "Pathways Across Cultures," such as the author(s), publication year, publisher, and place of publication, I can give you a template:
Author(s) Last Name, Initial(s). (Year) Pathways Across Cultures. Place of publication: Publisher.
Once you have the specific details for the book, you can fill in the template accordingly. If you provide me with the details of the book, I can help you create a more accurate reference.
