Disable auto complete on authors/contributors fields

Hello,

We're using OpenScholar, a Drupal 6.x distribution that uses the Biblio module extensively to allow the creation/management of user bibliographies. They seem to be relying nearly entirely on Biblio to do the heavy work of this.

Our issue is that we need to disable auto-completion on the Authors/Contributors form field, which lets you add fields via a "More Authors" button. We're able to disable auto completion on the first field either manually with form_alter or by disabling auto completion in the Biblio module settings.

However, this only removes auto complete on the first field - when you hit More Authors, it adds more, which have auto complete. No idea how to remove it from those fields.

Any ideas?

Thanks very much.

Katie
