there are special streetcred laws in place that make putting your cd/dvd collection in alphabetical order illegal, as is putting your collection in any order that would be noticed by a women as sorted into order. the penalty for this crime is being single for the rest of your alphabetised life
if you do want to live a lonely existance until the rest of your life, OR you are married, then you miss off "The" at the start of titles, and miss of "A" at the start also.
i found that out after working in a record shop. after filing the stock, i found that most of the shelves were empty, but the A and T sections were busting at the seems. after being told how to do it properly i refiled eveything, but then i came across the band called "the The" which confused me, so i just chucked those records out to keep things simple
oh, and films with numbers as titles should be filed as if you typed the title in words, ie 7 is seven, 2001 is two thousand and one, so 7 goes under S and 2001 under T, and you miss the first name and file under surname for artists (followed by first name), unless the artist name is the name of the band, thus PJ Harvey comes under P, John Lennon under L, Michael Schenker Band under M. and if you are confused, just throw away the records as no-one will probably want to listen to them anyways
personally, i keep my collection in a style that most would call "a bloody mess", and can't find what i want when i want it, altho it means that from time to time you come across something you haven't played in ages. unfortunatley computer mp3s and divx is slowly destroying this special technique, so enjoy it whilst you still can
