Then I suggest you use BetterRed's (famous
) auxiliary bookinfo folders idea.
You will need to edit the Manage Authors value for each author. If you don't mind getting a fail instead of the default search, every time an author doesn't have authorInfo folders, then edit Preferences ==> Interface ==> Look & Feel ==> Book Details (tab)
Default author link template == C:\Path\to\libraryInfo\{author}
