Thanks for this fantastic update where I can now create a catalog of books with the press of a button and it stores it as an .epub file in my library ready to place on my reader!
Just what I wanted to do
The output shows all the comments I've saved on each book so now I can hunt through the .epub when I'm wondering what to read next.
For anyone who doesn't know, just open up Calibre and hit the down arrow next to the Convert E-Books button - select create catalog option.
