The problem expression, which removes the booktype from a title is:
Code:
([\([](?:epub|mobi|azw3*|prc|pdb|pdf|siPDF|rtf|cbr|fb2|(?:multi-)*html*|htmlz|tif|lit|odt|txt|docx*|lrf|[dmehpjlr].+,.+?)[]\)]|\.(?:epub|mobi|azw3*|prc|pdb|pdf|rtf|cbr|fb2|html*|lit|txt|docx*)$)
I'm sure there is a better way, but this works for me
