How to assign multiple author names for one article? Is there any way to mention two or more author names for a particular article in Drupal 7?

I need to add two author names for one article.

I tried to add two author names in the Author text box, separating them by commas, but it did not allow me to do this.

Is there any module or other way to do this?
My workaround for this would be to enable a user reference field with multiple allowed values on the content type you want to put multiple authors on. Then just disable display of authoring info on that content type and instead display the user reference fields.

There are some things that you can't do with this but if you just want to display or categorize posts by multiple authors I think this will work fine.
