If the report has a unique identifier number, use it in parentheses after the title. In this case, include a more specific description in the brackets than just [Industry report] as is often used elsewhere, because IBIS has risk and other reports as well as global, state, and other levels of industry reports, and sometimes the titles and numbers are the same.
