While looking at 'My Library' on Audible, get it to show all titles for all time, then use this script to store a list of normalized, deduped titles.

gistfile1.js

var titles = '';
$('a[name="tdTitle"]').each(function(el){var text = $(this).html(); text = text + "\n"; titles = titles + (text.search('Part') > 0 ? (text.search('Part 1') > 0 ? text : '') : text).replace(' (Unabridged)', '').replace(' Part 1', '')});
