There is never a reason to change it. If you are faced with 34 different authors on a publication, write them all down . Complete lists of multiple authors are one of the ways of uniquely identifying a publication. Always look carefully for actual people who are authors before deciding that a publication has a corporate author. Be sure to note when someone is an editor rather than an author, because virtually every citation style makes a distinction.
Some citation styles use that word, and others leave off the author altogether.
When it comes to bibliographic citation, the two most important pages of most books are the title page , and the other side, or reverse, of the title page. You might be tempted to get information from the cover or spine, but they are no more accurate, and sometimes less accurate, than the title page and its reverse. If a book has a corporate author, it will often be on the title page in the same position as a human author. Always use the most recent. In general, don't worry about capitalization, since it is usually specified by the citation style.
