Just to make your automatic problem more difficult:
1 character difference makes it a
different title:
Blue Moon
vs
Blue moon
vs
Blue_Moon
Eyball Mk 1 is a wonderful thing.
The other Gotcha
is I have 2 different books with the same title..Different Authors
Ouch!
Btw sort Authors first, then sort Titles
Calibre seems to bias the sort by the previous sort. (is this a Bubble sort?)
