Hi guys,
Just a quick question (I had a elobarate post but my pc had a blue screen

( )
I would like to make collections based upon the author's name. I prefer sorting my books that way instead of sorting them alphabetically. I want to seperate the authors from each other. So I want a Bukowski collection of ONLY Bukowski. I want a collection named Mark Twain with ONLY Mark Twain (no other author with the letter T)
The easiest way to those would be to make all tags = author name. But since I'm new to Calibre I dont know how to do this without manually editing all tags.. can anybody help me out?
Is there a way to automatically make the tag of all my books equal their author names?
