When listing titles alphabetically, if the title begins with "The", you ignore that and alphabetize starting from the second word.
For example, a story with the title, "The Blooming Sakura" should be filed under "B", not "T"; you file it as though the title was, "Blooming Sakura, the".
Also, when alphabetizing by a person's name, you alphabetize by surname, if given (pen names with only one name supplied, obviously are filed under that one name only).
