You can try the chain attached, and it shall produce a csv file containing author notes. (only for authors in selected books).

You can change the path for the csv file by editing the variable in the module.

Note: The chain merely repackages the code of the template function get_note written by chaley.

Edit 1: You can control whether the notes are plain text or html by editing the variable called plain_text in the module.

Edit 2: The chain should have been called "Export notes", but it is already past midnight here ...
