If I were starting from scratch, using CC and only doing wireless transfers would be tempting. But I have multiple devices, Wifi is problematic on a couple, and a wired connection or dropping things directly onto an sdcard mounted as a drive is simply faster.

You seem to be asking for an app that can extract all the calibre metadata from a set of books on the device. Some reader apps can extract some metadata, but I have never seen one that can extract all metadata. In fact, I haven't seen one that can handle custom columns at all.
I'm think what I'm asking for is something that can read metadata.calibre on device and display it. Poking around, it looks like it contains the basic data I want.

My use case is wanting to know what books are on device without opening my eBook viewer. I can look at /sdcard/Books in a file manager to get a files list, but that's insufficient.

I don't need all metadata just to see if a book exists on device. Title and Author would do in a pinch, but Size, Date added, Series, and Tags for classification would be icing on that cake. I don't need covers, custom columns and the like.

But either way such a thing doesn't seem to exist. (There are SQLite viewers/editors for Android and I've looked at several, but they don't do what I'd like.)

I find that lack mystifying, but I appear to be stuck with it.

Thanks for chiming in.
