Hi, everyone.

I am trying to better understand the Calibre design behind the virtual libraries and tags.

1) Is it possible to nest virtual libraries within each other, creating a hierarchy of tiered virtual libraries within a single, shared virtual library? For example, if I begin with one main root virtual library entitled Non-Fiction, could I then create sub-libraries within it: 1) History; 2) Science; 3) Philosophy; 4) etc?

2) Am I correct in my understanding that tags cannot be nested within each other? Do tags all exist on the same hierarchical level?

3) Are tags considered metadata? Is there a find-and-replace command within Calibre that might help me better manage the metadata -- including automated tags that I would like to reword (often resulting from Calibre's metadata searches)?

4) Does anyone have any overall comments or suggestions for best practices in setting up detailed virtual libraries and customized tags? I am especially interested in defining tags for genres in a way that can be organized into tiers, if that is possible.

Thanks for your help!
