How to cite a report jointly published by multiple institutions?

To cite a report authored by multiple institutions, list the institutions in the order they appear on the report's title page as the corporate authors. Do not invert names; list each institution in full followed by a comma. The institutions share authorship credit. List them sequentially on the title page, using their full official names separated by commas. Include the year of publication, report title (in italics), report number or series if applicable, and location details. Crucially, specify "Author" after the institution list in the reference entry. Provide a complete retrieval path if accessed online, such as a DOI, URL (preferably persistent), or database name, adhering to your required citation style guide's format. Most styles (e.g., APA, Chicago) utilize this corporate author approach for institutionally authored reports. When constructing the entry, locate the publishing institutions on the title page. Start the reference with these institutions followed by a period, designation of the year, italicized report title, report number (if any), and publisher/location details. Conclude with the access method: if online, include "Retrieved from" followed by the direct URL or DOI. Ensure the entire consortium or collaborative body responsible for the report is accurately reflected in the author field. Follow your specific style guide consistently.
