I noticed that there are 225 resources in my library without a listed author. Of course, there are a number for which this makes sense (35 Bibles, a Qur'an, etc) but the number includes 99 magazine volumes, 38 journal volumes, and 14 monographs (among others).
I do hope this tagging can be cleaned up/added in the near future!
Diagnostic Logs
I have 715 resources in my library without an author. As you state most of those are bibles and scripture text, but of the magazines which I have 275 is specifically Christian History and Christian Magazine, most of the monograph (312) is Perseus. As for the other stuff I really don't care there is an author or not, most all of it is Faithlife produced resources.
