All works pages and most indexes are supposed to contain lists of tropes in alphabetical order. Standards for alphabetizing may vary; to make things easier to find, we want to keep ours consistent, so please use the rules below even if you're used to alphabetizing things differently somewhere else.
Ignore articles at the beginnings of titles. That is, the words "a", "an", and "the". They're incredibly common and removing them doesn't usually change the meaning of the trope, so it's better just to pretend they're not there at all. For example, The Magic Goes Away should be alphabetized under M; A God Am I goes under G.
Do this even for foreign-language articles. The vast majority of all tropes with foreign-language names are in either Japanese or French. Japanese doesn't have any articles, so mostly this just means ignoring "le", "la", "les", and "l'" at the beginning of articles with French names. For example, La Résistance goes under R.
Be careful, especially with "a", that it's being used as an article in the trope name. For example, A-Team Firing is about The A-Team, not just about "a team", so it should be alphabetized under A.
Ignore spaces and punctuation. There are different English-language standards about what to do with spaces; this is the one that best corresponds with the way the TV Tropes internal database works.
Treat special characters as though they were the corresponding ordinary character(s). Mostly this is so accented and non-accented versions of the same name get alphabetized in the same way. For example, Ĉon Flux should be alphabetized as though it were spelled "Aeon Flux".
Alphabetize by custom titling rather than the database name of the trope. For example, 100% Completion should come before Alpha Bitch, since numbers are alphabetized before letters.
