When citing an open letter, is it appropriate to cite all of the signatories as authors?
I would like to cite the following open letter: Dear Oprah Winfrey: 142 Writers Ask You to Reconsider American Dirt
The letter has 142 signatories. The byline says it is by "141 Writers" with no particular author name. So would I cite the author as "141 Writers" or would I cite it as though the signatories are the authors?
This particular paper is in APA but I would be interested in information about MLA as well in case it comes up, since I use MLA in the classes that I teach.
