How to search/filter resources without author?

I have many resources that have no author. When I sort my library by author, those resources get dropped altogether.

Is there any option to filter just resources without author specifically? I just want to get an overview what's in there, and which books I don't see when I sort by author...

I am not sure I understand your question. If you sort by author, all of the resources that have no author are grouped together.

I'm not sure why. Below is a screen shot of my library pane sorted by author. As you can see the NIV is listed as part of the resources with no author identified.

I just realized that you are talking about the Android app. My apologies. I do not have an android device so I cannot comment on this issue.

Again, my apologies.
