-Having said that, you can probably (I haven't tested it myself) get the first one (`@book.authors.delete @tolstoy`) working with this [monkey patch](http://stackoverflow.com/questions/2381033/how-to-create-a-full-audit-log-in-rails-for-every-table/2381411#2381411).  Many thanks to Danny Trelogan for pointing it out.

+The difference is the call to `destroy_all` instead of `delete_all` in [the original](http://github.com/rails/rails/blob/master/activerecord/lib/active_record/associations/has_many_through_association.rb#L76-81).

 There may be a way to store authorship versions, probably using association callbacks, no matter how the collection is manipulated but I haven't found it yet.  Let me know if you do.
