Update interactive data issue - Systematic Theology

MJ. Smith

Systematic theology is not my primary interest but my library still has 230 books of type: Systematic Theology. However, my Systematic Theologies interactive has only 185 resources. Support info imply recent updating

but it seems to me that the interactive is missing a significant chunk of resources

However, my Systematic Theologies interactive has only 185 resources.

I see 187, but the point stands.

The 11 that I see with the era "Unknown" also suggest a problem with updates to this interactive, as do the 22 of type "Not Specified".
