Here's an (IMO) better set of regexes:

                (r'(?i)[({\[](\d{4}|omnibus|anthology|hardcover|paperback|mass\s*market|edition|ed\.)[\])}]', ''),
                (r'(\d+),(\d+)', r'\1\2'),
                (r'(\s-)', ' '),
                (r"'", ''),
                (r'''[:,;+!@#$%^&*(){}.`~"\s\[\]/]''', ' ')

You can add more words to the first regex if you think of any
