I make use of the Link column in the Manage Authors dialogue, over time I've populated it with different protocol links**
- I started with file:// links that referenced text files;
- After a while I converted to evernote:// links referencing sections in an Authors notebook.
- Due to changes in Evernote (it got clouded) I converted to onenote:// links,
- As soon as Kovid implemented calibre:// links I started converting the content of Onenote 'notes' into 'book' records in an Authors library. It was what I'd been yearning for all along, I wanted its extensible database (custom columns).
** - because I dislike browser user interfaces,
html:// links were never a consideration for
me.
