Too many contributors

Well, you can go to the Goodreads Feedback group and use the questions and suggestions folder to ask for more names being allowed. (Edit: I think this has been done; I don't remember the response, if any.)
In the meantime, I'd add in the first 30 as authors and the last 34 authors I'd put in the book description field. They won't be searchable but at least they'll receive credit for their contribution.
Thanks
