(granted, running on older versions of firefox, but still thought it might be a bug you would like to be aware of.)
If you use the https://openlibrary.org/volunteer page and click the Librarian link, this will send an email to Lisa, our head community librarian and we can help you access our slack channel and request access to our librarian features. We also have an optional weekly call for folks to raise issues and questions (e.g. "I want book series!")

If you hit any issues with this process, feel invited to send me an email to mek@archive.org.
Ideally, it should probably bring you to the login page and (once you login) bring you back to the import page.
We'll see about creating an issue for this, thanks!
